Audio Quality

The provider supports two quality levels with automatic fallback.

Quality options

Value	Format	Bitrate	Requirements
high	MP3	320 kbps	Any account
lossless	FLAC	Lossless	Zvuk Music subscription

Stream selection logic

When a track is requested for playback, the provider tries quality options in descending order:

With lossless setting:

1. Try FLAC (lossless)
2. If unavailable → try MP3 320 (high)
3. If unavailable → try MP3 128 (mid)
4. Last resort → stream.get_best_available()

With high setting:

1. Try MP3 320 (high)
2. If unavailable → try MP3 128 (mid)
3. Last resort → stream.get_best_available()

Notes

has_flac field

The Zvuk API returns a has_flac field for tracks, but in practice it doesn’t always reliably reflect real FLAC availability. Therefore the provider always tries FLAC first when lossless is selected — regardless of the field value. The field is used for diagnostic logging only.

• The selected stream is logged with format and bitrate
• If no stream variant is available — MA receives a MediaNotFoundError
