Yes, the tradeoff here is that if we keep every other sample exactly as is while upsampling, there is less work to do, but yes, this also means only 6dB at half the sample rate. Still for oversampling a saturation effect or similar it should be "good enough" while from a performance point of view a lot better than other resamplers (would still have to benchmark this to prove it, though).

PandaResampler 0.2.0 has been released. This is a header only library for C++ which implements fast factor 2, 4 or 8 upsampling and downsampling based on SSE instructions. I've developed the code for my DSP code in Anklang and SpectMorph. It might be useful for you if you have some DSP loop which needs to be oversampled to avoid aliasing. https://github.com/swesterfeld/pandaresampler -- Stefan Westerfeld, http://space.twc.de/~stefan ___ Linux-audio-dev mailing list -- linux-audio-dev@lists.linuxaudio.org To unsubscribe send an email to linux-audio-dev-le...@lists.linuxaudio.org

[LAD] [LAA] Anklang 0.2.0 Released
Anklang version 0.2.0 is released. Anklang is a digital audio synthesis application for live creation and composition of music. It is released as Free Software (MPL-2.0) and runs under Linux. The real-time sound engine is implemented in C++, the UI runs in Electronjs, Firefox or Chrome. Assistance with development, porting or creative efforts is very welcome. Anklang provides a MIDI sequencer, Undo/Redo capabilities for note editing, real-time synthesis, and support for CLAP plugins. The source code and binary packages are available here: https://github.com/tim-janik/anklang/releases/tag/v0.2.0 The project website with further resources is at: https://anklang.testbit.eu/ === This release has significant improvements to audio synthesis capabilities and user interface. The documentation has been improved in several places, and automated generation was integrated into the CI. Audio synthesis enhancements include support for new CLAP (draft) extensions, such as transport information and file references. We now support non-linear mappings for BlepSynth ADSR times, and a new audio plugin Freeverb by Jezar at Dreampoint was added, with fixes to the damping mode in the original version. Additionally, a Jack PCM driver based on Stefan Westerfelds’ code was integrated. Performance improvements were achieved by adding a new optimizing memory allocator and supporting low-latency scheduling via sched_* or RtKit. Saving projects will now automatically create backups of recent versions. The user interface has also seen significant improvements in this release. These include context help via F1 key in various UI components, fixes to mouse wheel sensitivity for modern browsers, improved tooltips and note editing in the piano roll. The UI can now be zoomed via new menu entries, the color palette was updated, and integration of TypeScript annotations allowed improving the UI JavaScript code quality. In terms of packaging, AppImage builds saw major compatibility improvements, and we increased the frequency of Nightly releases, building from nearly all significant trunk merge commits. We aim to generate more regular releases in the future instead of having lots of Nightly builds between regular releases. -- Anklang Free Software DAW: https://anklang.testbit.eu/ ___ Linux-audio-dev mailing list -- linux-audio-dev@lists.linuxaudio.org To unsubscribe send an email to linux-audio-dev-le...@lists.linuxaudio.org

Hi! Am 12.01.20 um 18:59 schrieb Benoît Rouits: > I will update QLiquidSFZ then, to reflect the additions you made. > Many thanks for this cool library. Right. The most interesting (difficult) addition from the UI point of view is probably >> - provide list of CCs supported by .sfz file (Synth::list_ccs) The thing is that CCs can be used to control aspects of the sound, such as panning or the number of layers used for the sound (i.e. some layers will be turned on/off by the cc). From an UI point of view it would be ideal if each CC was displayed as one slider (or knob), so you would call list_ccs and create a number of sliders/knobs, one for each CC. The default value provided by liquidsfz would be the initial position of the slider/knob. If the user turns the slider/knob, then qliquidsfz would generate CC events for it. Its a bit tricky because obviously Synth::add_event_cc() cannot be executed at the same time Synth::process() is running in the JACK thread. One way to do this is using some kind of queue for the CC events, so that the JACK process callback can execute them together with the other midi events before process(). Also in a perfect world if CC events were be received by MIDI, the UI would update its state. So using an external midi controller would move the Qt slider/knob widget. Again, this needs to be implemented carefully in order to be thread safe. The CC widgets really cannot be done properly by the text UI, this is why I only display a list there. If you are looking for a program for inspiration how a UI could look, I'd recommend sforzando for windows. This can at least give you an idea of the direction to go. I personally obtained an old version (win_sforzando_v1.822.exe) which runs in wine. You'll see in the controls tab what I mean if you load a sfz with CCs. Cu...

Overview of Changes in spectmorph-0.5.0: * Support user defined instruments - graphical instrument editor - new WavSource operator * Make standard instrument set smaller (less download/disk usage) * Graphical ADSR editor * Added "SpectMorph User Manual" (online: html/pdf) * Use different colors for active/used/unused operators * LV2 now requires instance access feature * Add file dialog wrapper shell scripts to work with some ardour bundles * Integrate XML (pugixml) and ZIP (minizip) 3rd party code * Minor fixes and cleanups What is SpectMorph? --- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 Integrating SpectMorph into your Work - SpectMorph is currently available for Linux and Windows users. Here is a quick overview of how you can make music using SpectMorph. - VST Plugin, especially for proprietary solutions that don't support LV2. (Available on Linux and 64-bit Windows) - LV2 Plugin, for any sequencer that supports it. - JACK Client. Note that at this point, we may still change the way sound synthesis works, so newer versions of SpectMorph may sound (slightly) different than the current version.

Right. This particular "cleverness" would be wrong for the SpectMorph plugin as well. Computing the audio data is quite CPU intensive, so if you would instantiate it twice, you'd be wasting precious resources (for computing the same data twice).

Ok, I tried that, and this produces the intended result. If you as host author say that this is the way Qtractor users should go for mono instruments, I'll keep my plugin as it is, the other way would have been kind-of a workaround. Still from the user experience I prefer what Ardour does, as it automatically gets the intended result without the user needing to do anything. Cu...

[LAD] LV2 mono instruments recommended?
Hi! I'm currently implementing a LV2 plugin for SpectMorph, and so far I only defined one audio port in the ttl file/source, as the output of the morphing algorithm is just mono. I have tested with Ardour and Qtractor. Ardour does what I'd expect: it plays my instrument output on both channels. Qtractor however just plays my mono data on one channel, the other is silent. Which is not what I want. So I am considering making my LV2 instrument always stereo, and just copy the output buffer from left to right - this is cheap, and probably not much more expensive than what the host would need to do anyway. Does this sound like the reasonable way to go? Cu...

The problem is that the three backtraces you sent me point to different locations; one of them actually has a gst123 function in it, the other two backtraces only include symbols of the gstreamer libs. Now of course it could be that gst123 does something wrong (has a bug), and that only some time after the actual bug occurred an unrelated function crashes due to memory corruption. Or it could be that gst123 has nothing to do with any of it, and that some part of the GStreamer framework causes the crash; for instance a decoding plugin, an audio driver or whatever. So one way to proceed would be to try to reproduce the same bug with another GStreamer based player. If that succeeds, gst123 is not the problem. If it fails, we probably cannot say for sure if gst123 is the problem, because gst123 may be using GStreamer in a different but equally valid way. In any case, your stack traces have given me the opportunity of reading the code in gst123 a few more times, and I've done two changes; one of them should make gst123 abort with an assertion if the code is problematic, the other change should fix a possible crash, but I am not sure if that is the crash you had. But it would be great if you reran your test with the newest gst123 git version. Generally, valgrind would also be a great tool for debugging such problems, however, I suppose it won't be fast enough to play your radio stream... Cu...

Hi! On Wed, Jul 07, 2010 at 12:42:38PM -0700, Niels Mayer wrote: Thanks for your help and response... FYI, here's a few bug reports/feature-missing things: (1) I finally figured out those flashing squares that appear every time gst123 changes songs. It's album-art images, displayed in an X window! These need to stay up longer, as only by forcing the audio device to be busy and playing back a giant directory of files, I was able to actually see that these are windows containing images, and not some weird new display-glitching bug caused by KDE's Smooth Tasks widget. To be useful, the display of the image needs to be held for a certain amount of time after you're sure the window-system has actually rendered the image. Perhaps a single integer option --albumart-time -- when set to 0 image display is suppressed, otherwise, an integer like 1000 which would hold the album-art image for 1 second. (And yes, I realize that a fix for this issue is easily had in my script play-cd (shorthand for play sound only @ 44.1, vs play-tv w/ X/Video @ 48k): | #!/bin/sh | args=`/bin/ls -d $*` | export DISPLAY='' | exec gst123 -a alsa=mythcd $args ) I didn't explicitely do anything to make the pictures come up. Its just that gst123 will try to decode everything that is on the play list, audio files, video files and other files. Normally other files are not a problem, because gst123 will detect that it can not read the file, and remove it from the playlist. However, GStreamer will decode images like album art, so they are flashing up, and once the decoding is done disappear again. I am not sure yet how to fix this. One could simply blacklist some filename patterns (like *.jpg, *.png, ...), but then again, a file called this way could theoretically contain an ogg file. Also the blacklist might not be complete. So what would be better would be to use the same strategy GStreamer uses to figure out the right decoding object, and then blacklist some of those. In any case, I've added this item to the TODO, and of course I'll also accept patches. (2) Sometimes video windows come up at the wrong size (tiny). You can resize them with the window manager and resize it back and get the correct aspect. Or you can quit and run it again and find it sized correctly. I had hoped that this would no longer be an issue, because of the changes that I made some time ago. But if it is still happening, it should be fixed. You also may be able to correct this using the 1 or f keys. I've added this item to the TODO. (3) Is there a way to create a specific, stable, window-name for the video window created, perhaps settable as commandline parameter. That way for captions, you don't really need to worry about overwriting the video with transparent letters like you would on an actual TV caption. Instead, wrap your program in an external program such as Python, or WINTERP (*) that captures the video window (much like a window manager would, or how mplayer windows are displayed insider wrappers like smplayer kmplayer etc) and parses the time-data-stream information continuously output by gst123. Below the video window you stick a text widget and display caption text independently of the video. There's really no need to overlay and worry about transparency mapping through letters and slowing down the rendering, and all that potential, hardware-dependent fail. Stick the text in a GUI toolkit where all the region and language issues can be handled appropriately... Such tools are happy to update a few times a second to display new captions while X is off rendering the video (or stepping out of the way) in the most efficient, platform-independent manner available. Right, it might be nice to have a window title parameter which can contain some special sequences (like %f for the filename being played, or %t and %T for time and total time), so that the window title can be used to output something useful. However, I think that gst123 should be able to display seek position without any extra programs, because most users will just install gst123 and use it as it is. About winterp: looks like a program which could be used to do some interesting things. However, I would recommend using something else as scripting language, not scheme. My experience with scheme is that it is so totally unlike most programming languages, that you need to think a lot more to get anything done or understand any code, even if you are normally good at programming. Python might be a better choice, because it doesn't have such a different structure than C / C++ / Java (which many programmers know already). Cu...

For example: do it once at application startup, or even better, a way to prevent it from happening all-together via environment variable, configuration, etc. Best would be some kind of environmental check so that the timeout on socket needn't occur.The timeout significantly slows down operation of the program even when not issuing ^C's. Answering own question: The search for audio devices is bypassed by setting the -a commandline parameter to the ALSA device one wants to use. I wrapped it in a script to use w/ emacs' dired, etc.: #!/bin/sh args=`/bin/ls -d $*` exec gst123 -a alsa=mythcd $args /dev/null The next release, gst123-0.1.3 will have a ~/.gst123rc where you can put audio_output alsa=mythcd which does the thing you want. The changes are in git already. I've used scripts to wrap gst123 before (for crawling directories with find), but usually its better to put the functionality in gst123, because then its available to all users (not just competent script writers).

Website: http://space.twc.de/~stefan/gst123.php Download: http://space.twc.de/~stefan/gst123/gst123-0.1.2.tar.bz2 Stefan -- very nice and useful program. Thanks for making this available! FYI -- To compile on Fedora, I had to install the following to get 'configure' to stop complaining: 1) yum install 'gstreamer-devel' (obviously) 2) yum install gstreamer-plugins-base-devel (less obvious as config complains: No package 'gstreamer-interfaces-0.10' found // No package 'gstreamer-video-0.10' found ) 3) yum install ncurses-devel gst123 should normally point you to Debian packages if it doesn't find something, although currently it only does this for ncurses. I am not yet sure how to make configure.ac print out the right thing to install depending on the distribution. But I'd accept patches that solve this. Question: is there a way to disable checking for pulseaudio for each new file when specifying multiple media files. e.g.: gst123 *.ogg ? If at all, this could be fixed in GStreamer pulseaudio support. Except for the .gst123rc entry we already discussed. (2) For HD Video recorded off digital broadcasts, but not for regular def broadcast video, there's a problem when issuing the '-' (forward arrow) or '-' (backward arrow) commands to skip forwards or back: As you go forward, there's an increasingly longer delay before the audio syncs up and starts playing. Hit '-' a few times and the audio never seems to sync up, and sometimes the video stays paused on the same frame, even though the time display in the terminal continues updating. This also sounds to me like a GStreamer bug - probably you should repost the question on a GStreamer mailing list. gst123 is just a very thin wrapper that uses GStreamer for actual seeking and decoding, so if there is something wrong with some files, the most likely thing is that the corresponding GStreamer plugins need to be fixed. (3) Note that if the above file is played out of a list 'gst123 *.mpg' then at least it gets audio playback. The same file, started standalone, shows video, but gives plays no audio: . gnulem-346-~ gst123 /home/npm/Videos/1551_20100407195900.mpg Playing file:///home/npm/Videos/1551_20100407195900.mpg ** (gst123:12323): CRITICAL **: gst_mpeg_descriptor_find: assertion `desc != NULL' failed Looks like a GStreamer issue, too. PS: Feature request: decode caption information from videos, and display in video. And/or output a timed-text, SMIL or other file containing the caption information and time-of-presentation information. This can be very useful in searching content of video files. I would accept patches for this one. Currently, I don't know what needs to be done to display anything on top of the video display. Could be that it can be done at Gtk level (we already have a Gtk window where we display things in), could also be that overlaying text or other information needs to be done with GStreamer somehow. Personally, I'd like to have a visual indication of the stream position during seek (and that is on the TODO), and once gst123 has the capability to draw on top of the video display, other stuff could be added.
