Merge WAV Files

How to merge WAV files

1. Add your WAVs. Drop two or more WAV files into the box. Each shows its length, sample rate and waveform.
2. Order them. Drag tracks by the handle or press A-Z to sort takes by name.
3. Choose the joins. Back to back keeps every sample, a silent gap separates takes, a crossfade hides the seam.
4. Merge. Keep WAV for a lossless result and press Merge. The file is written right in your browser.

Recorded at 48 kHz for video? Set Channels and sample rate to 48 kHz so the merged WAV drops straight into your editor timeline.

Truly lossless

WAV in, WAV out - with back to back joins the merged file holds exactly the samples of your recordings.

24-bit recordings are written as 24-bit WAV, everything else as 16-bit. Files with different sample rates (say a 44.1 kHz voice-over and a 48 kHz music bed) are converted to one rate with a clean resampler first, because a WAV can only have one.

Only volume changes you ask for - Even out loudness, fades or a crossfade - alter the audio.

How big will the WAV be?

The size shown after merging is measured from the real file. Classic WAV files stop at 4 GB, so for very long merges use FLAC in the FLAC merger or MP3.

Good to know

• Takes and retakes - use a 1 second gap so the edit points are easy to find later.
• Field recordings - a 2 second crossfade hides the jump between two recordings of ambience.
• Voice-over - Even out loudness keeps all parts at the same level.

Need just part of a take? Cut it out first with the MP3 Cutter, which can save WAV too.
