How to Convert Audio to WavPack with FFmpeg

Converting audio files to the high-quality WavPack format is straightforward using the powerful, open-source FFmpeg command-line tool. This article provides a quick guide on how to write and execute the FFmpeg command needed to convert various audio formats to WavPack, explaining the key command-line arguments for optimal audio compression.

To convert any audio file to the lossless WavPack format, use the basic FFmpeg syntax. The simplest command automatically detects the output format based on the .wv file extension:

ffmpeg -i input.wav output.wv

In this command, -i input.wav specifies your source audio file (which can be FLAC, MP3, M4A, or WAV), and output.wv is the resulting WavPack file.

Customizing the WavPack Compression

While the default settings work well, you can explicitly define the encoder and adjust the compression level to balance file size and encoding speed. Use the following command to set these parameters:

ffmpeg -i input.wav -c:a wavpack -compression_level 3 output.wv

• -c:a wavpack: Explicitly selects the WavPack audio encoder.
• -compression_level: Controls the compression effort. The values range from 1 (fastest encoding, larger file size) to 5 (slowest encoding, smallest file size). The default level is 2.

Batch Converting Multiple Files

If you have a folder of files you want to convert to WavPack, you can use a simple terminal loop.

For Windows Command Prompt:

for %i in (*.wav) do ffmpeg -i "%i" -c:a wavpack "%~ni.wv"

For Linux or macOS Terminal:

for file in *.wav; do ffmpeg -i "$file" -c:a wavpack "${file%.*}.wv"; done
