Re: 32k vs. 48k log and capture issues

[Michael G] "The nornal setting for HDV is two channel 16 bit 48Khz. "

I didn't know this!

[Michael G] "Internally the audio is recorded to tape as mpeg, but comes out as PCM 16bit 48Khz."

When it's recorded using MPEG-1 Layer 2, the audio bitrate is 384Kbps - which is a 4:1 compression over DV audio, which is using uncompressed 16-bit PCM at 1536Kbps. So while it may be sent out PCM 16bit 48khHz, it's sending out data that's already been compressed. (i knew there was some reduced quality issue with HDV audio, but I was thinking it was the 12bit 32kHz thing :-)
