Varying # channels and sample rate

Post by nahidalam » Tue Aug 30, 2011 4:19 pm

Hi,
I am studying the performance impact of audio playback with varying #channels and sample rate of the audio clip.
My goal is to vary 1 property at a time keeping others constant.

-I have a 6 channel 48KH wav file. I want to change the sample rate keeping that 6 channel. But audacity always converts it to 2 channel when I export. can anyone help?

I haven't tried this and I don't have a multichannel file handy...

Instead of WAV, select "Custom FFMPEG Export" (I assume you have installed FFMPEG). Then click "Options" and the FFMPEG dialog box pops-up, and you can select WAV, PCM, and other options.

To export a multi-channel sound file you need to go to:
"Edit menu > Preferences > Import/Export"
and select the option "Use Custom Mix".
