I use fre:ac if I want to combine several MP3 files into a single M4A file and create a cue sheet for easy access. :)Ī specific application, where the merging and splitting of MP3 files without re-encoding is a useful feature, is dealing with audiobooks, which also ties into my request for the expansion of fre:ac's cue sheet handling abilities. Not to take away from your efforts to get fre:ac finished, but. So I added this to my list of things to do after the 1.1 final release. This would not be a lot of work, but I would like to concentrate on getting fre:ac 1.1 finished now. I imagine there could be a "Generate cue sheet" item in the "Encode" menu that would generate and save a cue sheet based on the current track list. After all, re-encoding lossless audio is usually very fast and as it's lossless, there is no generation loss.Īs for #2, that's a valid point. However, separate implementations for each format would still be necessary and the benefit would likely not be worth the hassle. With lossless codecs it might be a bit easier as their blocks are usually independent of each other.

For example, mp3DirectCut supports concatenating MP3s without re-encoding.

So this is better left to specialized software in my opinion. So it would work for most studio albums, but not for gapless track transitions or live albums. It would make some sense only in one case: When there is silence between the concatenated MP3s and it does not matter if that silence will be slightly longer (usually less than 0.1s) than on the original album. When concatenating two already encoded files, these empty samples would appear at the tie point and could cause all kinds of clicks and pops during playback. Special metadata in the file header indicates the amount of empty samples present, so an application that supports gapless playback can skip over them. The samples at the end are use as padding to the end of a block. The samples at the beginning are used to prime the filters used in the analysis stage. Lossy formats such as MP3 or AAC usually contain some silent samples at the beginning and end. Regarding #1, that would technically be possible only in very specific situations. Thank you very much for even considering my requests. If you are not able to add these capabilities to fre:ac, if you could point me in the direction of a method or another piece of software that could accomplish the tasks, I would really appreciate it.

The other would be if I had a group of separate files and I just want to see what the cue sheet would look like, including accurate times, IF I merged them, without actually doing the merge. One would be if a cue sheet is already embedded in an m4b, and I just want a separate, external cue sheet. I personally would be interested in using this feature for m4a and mp3 files, but I can definitely see it being useful for other formats as well.Ģ) Occasionally, I could really use a way to just create an external cue sheet, without any encoding actually being done. :)ġ) I'm sure this has been asked before, but is there any way that if you are merging multiple files of the exact same format, codec, bitrate, etc, that the merge could be done without re-encoding? Both for speed and to prevent further loss of quality if a lossy format such as MP3 was involved. I do have two requests, one of which I know has already been asked at least once, but I'll ask again.

Fre:ac is a great product! I don't kow why it took me so long to find it.
