A good merge sounds like one piece of music, not two files stuck together. This guide walks through the same steps you follow in the Music Merger.
Step by step
- Add every song you want. Up to 20 files can be loaded.
- Cut each song to the part you need by dragging the cyan handles. Pick endings that finish a phrase rather than stopping mid-note.
- Order the songs with the drag handle or the arrow buttons. The merge bar shows the final order.
- Press Match loudness so one song is not suddenly louder than the next.
- Set the crossfade. Start with 3 seconds and press A/B to compare it with the original hard cuts.
- Export MP3 for sharing or WAV for further editing.
How a crossfade works
During a crossfade the first song fades out while the next fades in over the same few seconds. With the Equal power curve the combined loudness stays steady in the middle of the blend, which is why it is the default.
Making it sound smoother
- Join songs with a similar tempo and energy.
- Use a longer crossfade only when both songs are steady in that section.
- Listen with headphones for clicks or doubled beats, then adjust the cut points.
Tempo estimates are only a guide. When the studio cannot estimate tempo reliably it says so and skips tempo matching. Related: Crossfade Mixer, Volume Normalizer.
Frequently asked questions
What is the best crossfade length?
Between 1 and 3 seconds works for most mixes. Use 6 to 10 seconds only when tempos match.
Can I merge MP3 and WAV files together?
Yes. Every file is decoded first, so mixed formats are fine.
