Quality selector information:

Quality selector allows you to choose from the four different streams Tidal has to offer.

Tests were made with the song Clocks from Coldplay for comparison. More details about each one below:

• Master (MQA): Lossy codec that promises to deliver the best sound quality. FLAC container. FLAC audio codec. 932 kbps. 34.4 MiB. Mediainfo
• HiFi: True CD-quality stream in a FLAC container. FLAC audio codec. 932 kbps. 34.4 MiB. Mediainfo
• High: High quality stream in AAC-LC for wider DAP support. MP4 container. AAC-LC audio codec. 320 kbps. 12 MiB. Mediainfo
• HiFi: Standard quality for users with limited space. MP4 container. AAC-LC SBR audio codec. 96 kbps. 3.53 MiB. Mediainfo

Experimental Opus and MP3 support has been added. These are transcoded from the HiFi (FLAC) files straight from Tidal after being downloaded.

Opus is encoded using opusenc (libopus 1.3.1) and for MP3 we are using ffmpeg's Lavc59.18.100 libmp3lame encoder.
