I recorded a show last night and tried to edit the tracks

I found that the recordings play in Media Jukebox, Real
Player, and the Archos.

BUT...

and was unable to load the mp3 files in either
Soundforge or MP3 Direct Cut for editing.

Record settings: Quality - 7
Frequency - 44.1
Source - line in
Channels - stereo

This bug report is about the initial zeroes that linus later
fixed to create an id3 tag instead.

If you experience OTHER mp3-related bugs, file them as new
bug reports.

Smallest mp3 of listed files is 730KB.
Can not attach.
Reach me via e-mail I will foward.

This is because files recorded with Rockbox reserve 4Kbytes
of data in the beginning of the file for ID3 info plus a
Xing header. This block is currently filled with 0's. That
seems to confuse those editors.

Some day we will add real ID3 tags...

The latest daily build adds an ID3 tag instead of just 0's.
How does you editor handle it?

More discovery of mp3 recording revealed a silent section of
the recording at app 1 hour into the second set. It sounds as
though the disk did not respond fast enough for the data.
Listen to the attached mp3 for the error.

I am experiencing the same problem:
MAGIX Audio Cleaning Lab 2004 does not open the MP3 I
recorded.

Archos Recorder 20.
Rockbox 2.0

use mp3 tag tools from http://sourceforge.
net/projects/massid3lib to remove the id3 tags, works for me.

not a proper fix to the problem i know but it does the trick.
