FAQ for portable FLAC players buyers:

Is a FLAC file better than mp3?

While FLAC files are up to six times larger than an MP3, they are half the size of a CD and can have the same boost in audio quality. Furthermore, FLAC is not just restricted to 16-bit (CD quality), and you can buy files up to 24-bit/192kHz for another potential boost in performance.

Is FLAC the highest quality?

FLAC: Studio master sound quality (24-bit) and CD-quality (16-bit). The 24-bit/192kHz versions are the highest quality files commonly available and are identical to the studio master. Unlike MP3, which throws some content away to reduce file sizes, FLAC is lossless and works as a computer zip file.

Can I convert mp3 to FLAC?

Convertio is an audio format that allows you to convert MP3 to output formats like FLAC, OGG, AAC, WMA, WAV, CAF, AC3, GSM, AIFF, M4A, and AMR. Click on Select Files to Converter and upload your desired MP3 file. Next, choose FLAC as your output format. Click on Convert to proceed.

What is the highest audio quality?

A lossless audio file format is the best format for sound quality. These include FLAC, WAV, or AIFF. These types of files are considered “hi-res” because they are better or equal to CD-quality.
