Splitting a large MP3 file into tracks

Encoding as MP3 loses information.

Most editors need to decode MP3s before they can be edited, so if you edit an MP3, then save or export as MP3, the audio has to be encoded again, which loses some sound quality. The lost quality cannot be recovered.

MP3directCut and MP3split are unusual in that they are able to perform simple edits of MP3 files without decoding the MP3s, so there is no re-encoding, so no additional sound quality loss. (Note that the Windows installer version of MP3split may contain adware).

WAV, FLAC and AIFF are "lossless" formats, which means that if you export in these formats after editing, there is no additional sound quality loss.

Audacity is able to analyze tracks to find silences and mark the silences with labels (see: http://manual.audacityteam.org/man/sile ... ml#silence).
When the gaps in the track have been labelled, you can then export each labelled section using the "Export Multiple" feature: http://manual.audacityteam.org/man/export_multiple.html

I am converting my cassettes to digital through audacity. Can they be initialized as something other than MP3 when I do this? Choose WAV at the time? Can I convert my preexisting MP3 files to WAV files and then manipulate them without loss?

OK so audacity has silence finder. It gives an output of a graphic with a lot of flags for silent moments. Can it make the tracks into files for the output? In the form I see it it is unwieldy for my purpose.

Does waveform lose information on processing?

Yes you can export each labelled section as a separate WAV file with "Export Multiple". See my previous post for details.

Does waveform lose information on processing?

Not if you export as WAV.

Can audacity output a file of split fragments of the whole file based on silence detection? Or are you doing a multi click process for each fragment?

Can I convert my cassettes to WAV through Audacity instead of MP3? Will they be much larger than the MP3 and not have lost that information?

I'm editing my own cassette tapes converted to MP3. Audio diary and music. I might have 100 cuts to make on a tape.

Use mp3DirectCut. That way you won't lose quality rewriting the MP3s as you will with Audacity.

When I'm installing and I get to extraction path I get access denied (invalid characters) when I try to DL MP3cut. Any idea?

MP3DirectCut is not our product and we do not provide support for it. However it does work as intended if you follow normal Windows permissions protocols.
