Ondesoft Audio Recorder For Mac is a great recorder. It will not change the original effect of the audio. It is just as good as Rogue Amoeba's Audio Hijack Pro.
However, the "editor" function is not so effective, it only allows to trim files, no other functions available.
All in all, it’s good for recording, but the editor function is not so good. You can only use it to remove the start and/or end part of the recorded file.
