Strange sound at playing 8bit sound #16

Open ghost opened 8 years ago

ghost commented 8 years ago

When I play the sound file@8bit 22050Hz (e.g. "The Microsoft Sound"), Sanear renders strange sound.

Can you upload it (or a sample) somewhere? I could only found 16bit 22050Hz wav files in c:\Windows\Media\ on Win8.1 .

Cheers, I can confirm the problem with 8bit 22050Hz. Although it's working fine with 16bit 22050Hz.

Thanks and Sorry.

I newly discovered some things.

The sampling rate is not unrelated. When I play the sound@8bit 44100Hz and 8000Hz, It was same strange sound. I guess Sanear can not render all 8bit sound. (Sanear cannot extend bit even though can resampling?)

and we can avoid this problem by disabling 8-bit output of LAV Audio.

Good idea for now.
