MP3 Question

[Wetling]

I have two MP3 files, the first one is a song ripped from a CD at 44.1kHz and 128kbps. The second one is the audio for a TV show I recorded in PCM and converted to MP3 at 44.1kHz and 128kbps.

The second MP3 file sounds very grainy, while the first one sounds fine. Why?

How did you record the audio from theTV?

The second MP3 file sounds very grainy, while the first one sounds fine. Why?

Because the first one is a digital source being converted to MP3 and the second is an analog source captured and converted to digital by your sound card. Better souce = better sound.

I have found that TV audio can sometimes be really crappy. I once tried to record a concert by using the audio output of my satellite receiver (digital remember?) and the noise in the background was terrible. I found however, that my PCM recording was bad even before conversion to MP3.

Check to see if your original wave file sounds good.

The PCM file sounds much better.
