A customer has an audio that is confidential and can't send it to me. He also doesn't want to install any tools.
Is there any way to tell whether the recording is one channel or two channel?
Normally, I would just get the audio and SoXI it. Alternatively, I would tell him to install Audacity or an equivalent sound editor and open it up. I also thought that if you right clicked and looked at the size, bit rate, and length, you could get the number of channels. But, the bit rate already factors in the number of channels.
