Can you put the files online somewhere so I can download them and test them?
Of course:
this plays fine: http://romanhaefeli.net/8ch_does_play.wav
this plays, but no sound: <don't know if i can post that link on the list>
Why does that link not go through to the list? hmm.
Anyway, if you set up readanysf~ with 8 channel output, both DO play just fine. The second one is playing, but is VERY soft....just jack up the amplitude multiplication on it. Readanysf~ doesn't normalize your audio for you.
BTW: Is there some documentation about how [readanysf~] (or the underlying layer) tries to assign the channels, when the number of channels created and the number of channels of the loaded file do not match?
no. this is all undefined as it comes from gavl. Thank you for bringing it up though. I am now in discussion with the developer about making an arbitrary mix matrix for mixing channels. I also found a bug in gavl that makes readanysf~ crash if you start it with, say, 4 channels, but feed it an 8 channel audio.
So, this will have to change for the next version.
Here is what I plan...let me know what y'all think.
Because of how PD works, I can only define the number of out channels at object creation. (right?) I cannot match the output number of channels to the input number of channels for any given file.
The way I would like it to work by default is:
for mono output: * for all input except stereo, just the first channel is played * for stereo input, it is downmixed
for stereo output:
* mono input will be upmixed to stereo
* 3 or more channel input will just drop the channels after the
first two
for 2+ channel output: * mono input is upmixed to stereo, remaining channels are empty * if input has less channels than output, all input channels are sent to output in order. any remaining output channels are left empty * if input has more channels thant output, all output channels are filled with corresponding input channel. the remaining input channels are not sent to output.
I don't know if it makes sense to have special default cases for mono and stereo.
