As we all know, WAV files are typically so large in file size that they take too much space or unable to send via email. Therefore, we may need to reduce WAV file size. The following article just aims to provide 3 methods to easily compress WAV files on Windows or Mac.

  • Compress WAV to lossless compression audio format without losing audio quality like compress WAV to FLAC, compress WAV to Apple Lossless ALAC M4A
  • Compress WAV to lossy audio format like compress WAV to MP3, compress WAV to WMA, AAC, RA and etc.

Method 2: Lower WAV bit rate

  • With this method, we can easily reduce WAV file size without changing WAV audio format.
  • The lower the bit rate, the smaller the WAV file size, the lower quality of the WAV audio.
  • In most cases, WAV audio quality shows little difference between 128kbps and higher bitrates. WAV quality will become crappier if the bit rate is less than 128kbps.
