How to make a DJ intro on your phone
Take an eight-bar intro from a file already on your phone and save a WAV to test it in your set.
Open single trimThe editor interface is in Spanish for now. Button names appear in Spanish, followed by their meaning in English.
Choose a track you already have on your phone
Save a WAV or MP3 in the phone’s file manager so you can open it from the Recorte (trim) tab of QuickEdit. For the first try, use a short file you know well. QuickEdit accepts WAV and MP3 files up to five minutes and 64 MiB each.
Trim from beat to beat
Listen for where the first beat of the phrase starts. At 120 BPM in 4/4, eight bars last 16 seconds. If the first beat you want to keep lands at second 12.40, the next boundary will be around 28.40. Use the start and end fields to mark those points instead of relying on hitting the waveform with your finger.
If the track has another tempo, divide 1,920 by its BPM to estimate the length of eight bars in seconds. Confirm the end by ear, especially if the tempo changes or the recording drifts slightly off the grid. The intro guide explains how to mark the phrase inside a session.
Check both edges before you take it
Listen to whether the intro keeps the beat and the end lands where you need it. If an edge clicks, try a short fade and listen again. Download the WAV with a recognisable name, such as intro-8bars-120bpm.wav. Then find the file on your phone and open it on the equipment where you will use it.
