Frequently asked questions
Does merging lower the sound quality?
Not when every file is an MP3 with the same sample rate and channels: choose Original and their audio is joined as it is. Otherwise the result is encoded once, at 128 to 320 kbps as you choose.
Can I merge files of different formats?
Yes. Mix MP3, M4A, WAV, FLAC, OGG and Opus freely; they are converted to the same sample rate and saved together as one MP3.
