Takes a LONG time to load audio files, then begins to play it automatically and takes a LONG time to stop when you press the Stop button (there’s no option to not automatically play the audio file you load). On cutting, it will only export the selected piece, if you want to split a file you have to input the first half to export it, then go back and input the second half; in other words, it keeps the original file intact and only extracts what you want. There’s no option to have it continually reduce the original file size by the portion you’ve extracted. This is really cumbersome if you have one long audio file comprised of multiple songs that you want to break into separate songs - you have to input the start and end time of each individual song to one-by-one extract the individual songs. It doesn't continually reduce the audio file size by virtue of a song you’ve just extracted, making the next song the beginning of the remaining file.Do not recommend. Try NCH’s Wave Studio instead.

I have to occasionally join a bunch of audio files from CDs I import into my Mac. This app has saved me a ton of time instead of manually joining the audio files with GarageBand. I would highly recommend it, and the 99 cents easily paid for itself the first time I used it.

It does what it says it does and does it well. And it's free! Better than many paid apps.

Try to joint my audiobook files. And the new output file can only play the first part and not continued. Try MP3 Trimmer by deepNiner, work perfect for me.
