Updated October 2026 · Audio repair and clean-up
A dropout is a sudden gap or cut-out in the sound, often caused by a loose connection, a wireless signal problem or a recording buffer error. Check the cause first, then repair a short dropout by filling it with a matched piece of room tone or by repeating a clean word, if the content allows.
A dropout is a short moment where the sound disappears or cuts out for a fraction of a second, then returns. It can sound like a stutter, a missing word or a digital hiccup. Dropouts are frustrating because they often happen once, and nobody notices until playback.
Check the connection between the microphone, the cable and the interface. A wireless microphone can drop out when it moves out of range or meets interference. A computer that is busy can cause a buffer error. Check the recording settings, the buffer size and any power-saving options on the computer and the USB devices.
Listen to the whole take, not only the part you noticed. Dropouts can be short and easy to miss, so zoom in on the waveform to see flat sections. If the dropout is in a quiet pause, the repair is easy. If it cuts a word, the repair is harder, and a re-record may be the better choice.
In a pause, fill the gap with a short piece of room tone from the same recording. Copy a few seconds of quiet, match its level, and crossfade both ends. Listen for any change in the room sound. The room tone post explains how to capture usable room tone.
If the dropout cuts a word, you may be able to repeat a clean word from elsewhere in the take, but only if the pitch, speed and emphasis match. Otherwise the join will be obvious. Re-recording the phrase is often faster and sounds better.
Keep wireless microphones charged and close, and test them before recording. Use a stable buffer setting, and close heavy programs before a session. Record a short test and listen to it before a long take.
Repairing a dropout is a short-term fix. If the problem is the equipment, it will return. Fix the cause before the next session, so you do not spend hours repairing takes.

Not always. Buffer errors and busy computers can cause them too, so check the settings.
Zoom in on the waveform and look for flat sections, or listen closely to pauses.
Only if the pitch, speed and emphasis match. Otherwise re-record the phrase.
It can, if it moves out of range or meets interference. Test it before you record.
