Why do I need to use an audio converter?

Maztr uses 2 main audio file formats — WAV and MP3 — however sometimes you may have audio files in other formats. Our Audio File Converter makes it easy to convert them to the format you need.

Which audio formats are the best?

Audio formats come in two categories — "lossless" and "lossy". Lossless formats are best because they maintain the full audio quality of the original source material, whereas lossy formats delete data to reduce file size at the expense of sound quality.

WAV files are lossless and the format we recommend for Mastering, however other formats such as FLAC and AIFF are also lossless. On the other hand, file formats such as MP3, AAC and OGG are lossy so they are not recommended for music production, particularly when Mixing and Mastering. They are best used where smaller file sizes are important or when sound quality doesn't matter so much, such as playing music in the car.
