Strange noises when recording to mp3
lee321987:
I'm getting noise whenever I encode to mp3, regardless of the bitrate. The noise sounds like what I hear when I encode (on my computer) at very low bitrates (e.g. 8kbps).
I have two Sansas - c240 and c250, and I'm only getting this effect on the c250. This noise is not present if I encode to the other available formats (AIFF, WavPack, PCM).
Some strange things I have noticed:
-- While recording on the c240, with Gain set to 0.0 dB, during silence the peak meter rests very close to the second dot (between the left and right meters), but if I turn the Gain UP to 6.0 dB the meter rests off the screen.
-- While recording on the c250, with Gain set to 0.0 dB, the peak meter rests between the 4th and 5th dots (this is regardless of the format I'm encoding to, but as I said, playback is noiseless if I use another format).
Any ideas?

Can you attach an example MP3? I'm very curious to have a look/listen.

I tried, mp3 is not an allowed file extension. I wonder if I'd be allowed to post an mp3 that I have changed the extention to .txt...?

The forum moderators don't like people doing that, the restrictions are there to save space and bandwidth.
Upload the file to a file-sharing site and post the link here.

Thanks.
Ok, here's the link, you'll have to turn the volume up pretty loud to hear the noise, BUT BE CAREFUL --- THE FIRST SECOND AND LAST TWO SECONDS CONTAIN MY BUTTON PRESSES WHICH ARE MUCH LOUDER THAN THE NOISE!!!
