Hi
Simple question here.
How are you testing the audio conversion? Do you record a audio file and save it in the different formats supported by the CODEC? Which tools are you using?
Regards
David McKenna:
Hi Martin,
Just right click on any audio file, there should be a 'Convert to' choice in the menu. Click the arrow to the right and you get a menu of choices to convert to. Pick one, then see if you can play the file that was created.

Yes. The addition of new data subtypes (samplerate/numchannels/bit depth combination) to MMPM (done via SPI.INI) is independent of any specific audio driver but is a necessary precondition to use that combination at all.
But of course, the audio driver also has to support that sample rate/bit depth/numchannels combination.
In short, the update package to SPI.INI contained in USBAUDIO will satisfy the prerequisites so that for example UNIAUD could use those new subtypes.

I'm able to play 24 bit, 48khz files here from the WPS using the USBAudio/USBWav driver, but not when using UniAud, even though the hardware supports it. I guess the UniAud driver does not support 24 bit files? Tried several versions of UniAud but no go.
However, I can play 24 bit files up to 192khz in dooble at this web page: https://www.msbtechnology.com/support/bit-perfect-testing/ . If I download one of these files, then double click on it in the WPS, it does not play.
I'm wondering if anyone has been able to play 24 bit or higher res files directly from the WPS using UniAud when they have the USBWav driver installed too...
Regards,
P.S. The new AIFF codec works well, thanks!, but only with 16 bit files too.

I installed USBAUDIO driver but 24bits do no play under WPS but are ok under PM123 kike DSF64 1bits are played too under PM123!
It looks like the maximum I could play are 16 bits 48Khz audio files.

Thanks for the feedback.
I grabbed Aplause.wav and convert it to OGG. It was fine and I was able to reproduce the converted file.
What it didn't work was to convert it to FLAC. I also did the "Convert To", but this time, when I press the convert button, the bar will not progress, the error sound will chime and the audconv.exe program will be unresponsive and I require to kill the process. It generates a 0 bytes FLAC file that of course don't work.
Any other conversion testing that can be done?
Regards
