Pretty sure lossy, but more info appreciated
This live show comes to me on audio CD from a guy who normally ONLY trades lossless. The SA of the wav certainly looks lossy, though - blockiness, clipped. Any idea, though:
Why the freq would cut at 13K? I thought mp3 usually cuts about 16K. What are the spikes that occur approximately once every 1/3 sec? Just curious here. TIA - Scott No members have liked this post.

Re: Pretty sure lossy, but more info appreciated
any mp3 encoder I've seen uses a default setting that makes the frequency cut at 16kHz, that's why its it most common. This is a lower-bitrate mp3, lower quality than average! The spikes are digital errors caused by being on audio cdr, slightly scratched, poorly extracted/copied etc.
