How to use this tool & FAQs

Join recordings into one audio file

The audio joiner places your uploaded track first, followed by the files you add in order. Crossfade overlaps the transitions instead of creating a hard cut between clips.

  1. Upload the first recording and add the remaining tracks in order.
  2. Choose a short crossfade or set it to zero for a direct join.
  3. Process and listen around every transition before downloading.

Tracks with very different loudness may need Volume & Fades adjustments before joining.

How many tracks can I join?

Up to ten tracks, totaling at most 30 minutes. File size and available browser memory also apply.

Make your next mix.

One track, many ways to make it yours.
Get a better result

Make a karaoke backing track

Open Vocal Remover and choose a stereo song. Choose Fast AI and preview 10 seconds. Quality AI provides a slower alternative for difficult mixes. Listen to the instrumental before processing the full recording. Complex mixes may still contain vocal traces or artifacts. Basic stereo mode is faster, but can also reduce centered instruments. Open Karaoke Studio with the result and use headphones while recording.

Cut a ringtone with smooth edges

Open Audio Cutter, enter the start and end times in seconds, then add a short fade. Listen to the exported WAV to check the opening and ending. Volume & Fades gives separate fade-in and fade-out controls.

Practice a difficult phrase

Choose Practice Room, mark the phrase, and slow the playback. Loop it while practising your voice or instrument. Use tap tempo to check the beat and Live Tuner for one steady note at a time.

Made for covers, practice, and your next idea.Contact
