Iím looking for a solution to split .MP1 audio files, at given time stamps, without re-encoding.
Use case: Converting Digital Compact Cassettes (DCCís) MPP files to MP1, then splitting albums into individual tracks.
I know that many years ago (late 90ís/early 00ís) some were able to split MP1ís using a program called ďMP3 SplitterĒ.
I have found a couple of old versions of MP3 Splitter, and am getting mixed results.
As well, Iíve tried using ffmpeg. However, whereas ffmpeg has an MP1 decoder, it does not have MP1 encoding capabilities - so, while I am able to split the MP1 into tracks, the split files are being output as MPEG-PS files instead of MP1.
Thanks in advance for any advice or recommendations.

What does you ffmpeg command line look like?
What happens if you used '-f mp3' or '-f mp2' for the output (assuming -acode copy) is used?users currently on my ignore list: deadrats, Stears555
Yes, I am referring to MPEG audio layer 1.
ffmpeg works well, so long as I'm okay re-encoding/transcoding. However; and I apologize, as this is a bit anal retentive on my part, I am attempting to just split the files without any re-encoding/transcoding.
ffmpeg -i input.mp1 -ss XX:XX:XX -to YY:YY:YY -acodec copy output.mpg
Despite being able to input .mp1, .mp1 is an invalid output format. I messed around and used .mpg output, which renders an mpeg audio file for which I can then simply change the extension back to .mp1, but in doing so, I believe I'm still getting a transcoded/re-encoded file. The resultant file has a slightly different bitrate than the original when I do this, and the file format, when inspected with MediaInfo, indicates it as an MPEG-PS file vs. MPEG Audio, which is what I begin with.

What's about mpa output?
