Pazera Free Audio Extractor takes the audio from most major video files without loss of sound quality or converts them to a variety of common audio formats. The program can also behave as a simple conversion tool from one audio format to another (e.g. AAC to MP3).
Some supported formats include (audio) MP3, AAC, AC3, WMA, M4A, FLAC, OGG, WAV, ALAC, WavPack, AIFF; (video) AVI, FLV, MP4, MPG, MOV, RM, 3GP, WMV, VOB, MKV, WebM and OGV.
Note: By default, the program will extract/convert to MP3. Select “Try extract original audio stream” to avoid re-encoding. This is faster, but may result in a format some devices can’t read. Additionally, the program has a number of predefined settings (profiles) specially designed for novice users. More advanced users can easily customize audio encoding parameters with output parameters.
