Re: [SlimDevices: Audiophiles] Touch: Upsampling with sox?
What format is the file? Are you running an external SBS or are you plugging in a USB drive to the Touch? Dou you get that message from the Touch or from the server? The Touch can definately play 88.2 files, and nothing in either Soundcheck's nor Dynaudiorules mods changes anything related to sample rate. I'm having a hard time figuring out how you would get that message. The file might be corrupt and give the wrong sample rate, but that should get caught by the server and converted to a supported sample rate (IF running an external SBS). The only other possibility I can think of is if you have SOX setup to change the sample rate to something the Touch doesn't support. I would check the server log and the Touch log to see if there are any errors reported when trying to play this file. The server log is listed in the server web interface somewhere under the advanced setup menu. On the Touch you need to SSH into the Touch (use PuTTY on windows) and cd /var/log less messages When done type q then exit to get out.

Re: [SlimDevices: Audiophiles] Touch: Upsampling with sox?
Hello, this is my first post, so please be kind.
In order to upsample Wav files to 48000 Hz PCM, the following file was
patched:
/Library/PreferencePanes/Squeezebox.prefPane/Contents/server/Slim/Player/Squeezebox.pm
This is on a Mac, but I assume finding this file on Windows should not
be too difficult.
The patch consists of adding two lines of code:
- one line to increase the bit depth from 16 to 24 bit
- the second to change/force the output rate to 48000 Hz
Here is the changed code:
sub stream_s {
# snip
if ($format eq 'pcm') { # unfortunately required for .wav files
# snip
if ( $track ) {
$pcmsamplesize = $client-pcm_sample_sizes($track);
$pcmsamplerate = $client-pcm_sample_rates($track);
$pcmchannels = $track-channels() || '2';
}
# Add two lines of code
$pcmsamplesize = 2; # 1;1-16 bits, 2-24 bits, patch
$pcmsamplerate = 4; # 3;3-44100, 4-48000 10-88200,
9-96000,
patch
# Upsample patch completed
The entry in the convert.conf file is:
wav pcm * *
# F
[sox_14_2] -q --buffer 32768 -t wav -r44100 -2 -c2 $FILE$ -t raw -C0
-3 -c2 -r48000 - polyphase -cutoff 1.0
Do add the line # F, for else no filename is passed to Sox, so nothing
can be upsampled.
Note:
Sox Version 14.2 is used to upsample, as this has the polyphase
option.
To use this, copy the version 14.2 Sox.exe file to:
/Library/PreferencePanes/Squeezebox.prefPane/Contents/server/Bin/darwin/
To distinguish this file from the distributed Sox.exe, the file is
renamed to sox_14_2.
I hope this does not look too complicated, and that it is of interest
for some people.

The music from the digital radio sounds 'warmer' than the cd's played back from the budget cd-player connected to the Meridian 568.1. Also, for 48 kHz material, the HS Out setting on the 568.1 makes an audible difference. For 44.1 kHz material I am unable to hear such a difference. This is my main reason to want to go to 48 kHz.

As you can see the flc pcm conversion rule outputs a
raw stream without a problem.
Code:

[flac] -dc --totally-silent --force-raw-format --endian=little

Based on above, I tried that one:

It is giving me static noise and my reveiver reports SR 44.1. Very

I tried your upsampling options, and I find the bass not synchronized

but polyphase is from older SoX releases, today it is just replaced by
'rate' effect

Re: [SlimDevices: Audiophiles] Touch: Upsampling with sox?
Hi guys.
For now I gave up on doing SRC on wav and pcm.
I also tried flac pcm + SRC.
Non of them I managed to get working so far.
Meanwhile I have converted my entire collection to flac.
This led to below working solution:
This is an adaptation from here:
http://forums.slimdevices.com/showpost.php?p=471468postcount=24
/etc/squeezeboxserver/custom-convert.conf
Code:
flc flc * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dc --totally-silent $START$ $END$ -- $FILE$ | [sox] -D -q -t

[flac] -dc --totally-silent $START$ $END$ -- $FILE$ | [sox] -D -q -t
wav - -t flac -C0 -b24 - rate -v -s -M -a 88200
As you can see I transform 44.1 into 88.2, which is preferable over
44.1/96 and I also changed some of the SRC options.
There is no need to do volume control here since we go from 16 to
24bits.
Dither is also turned off.
Check it out!
Would be nice if separate passthrough rules for 88.2 an 96 material
could be configured. Does anybody have any ideas how to do that?
Enjoy.
