I figured more than 60 minutes might take up a lot of disk space. But maybe compression solves that.

It needs to be at least 320kbps or the silence will contain audible distortion.

I'm sorry, but I only listen to silence if it's stored in 24-bit hi-res lossless FLAC.

Real audiophiles demand uncompressed WAV.

So you don't know what FLAC is, bit of a wasted joke

A real audiophile can hear the difference between FLAC and WAV.

A real audiophile is still waiting for their $4000/ft oxygen free speaker cables.
