If interested you can take quick look at what can be done with a modified version of omnitone for playback in a browser with different encodings. Headtracking is possible.
The decoder setup for each file decoding is controlled by a json file. I apologize in advance for the left right error ( to be corrected). Different encodings and codecs to try to find the optimum combination. No channel names are used, and care has to be taken to avoid LFE bandwidth cut when encoding. The implementation has somtimes buffering issues, but take your time to fill the cache for a few of the files. The software still needs a bit of work, Dash and HLS can be added. This supports foa,soa and toa with the addition of mixed formats. https://www.ohti.xyz BR Bosse On Tue, 2 May 2023, 14:12 Steven Boardman, <boardroomout...@gmail.com> wrote: > I agree that ATMOS delivery is more efficient, (stream size wise) but as > mentioned, it isn't great for anything other than theatres, despite what > Dolby and the rest of the bandwagon would like you to believe. > There is no below after all. > For non visual ATMOS delivery I purposely make separate static binaural > mixes, that are derived from native ambisonic/SPS mixes (rather than the > ATMOS binaural downmix). > So when an ATMOS decoder isn't present, the native binaural mix is served > up instead. > These are generally preferred....(I also do my stereo mix from the original > rather than an ATMOS downmix). > And as for audio mastering of the object based delivery, you can't, so most > separate stereo mixes i have heard sound better. > If a spatial 'scene' delivery is required, then maybe just use SPS, as that > should be more tolerant of compression ratios than Ambisonics.. > > Just my $0.01 > > Steven > > > On Mon, 1 May 2023, 22:05 Fons Adriaensen, <f...@linuxaudio.org> wrote: > > > On Mon, May 01, 2023 at 06:03:09PM +0000, Thorsten Michels wrote: > > > > > If a lower order is streamed, the other channels will be left empty, > with > > > digital "0", meaning absolutely NO signal.
