What is FLAC format:

FLAC(Free Lossless Audio Codec) is a lossless audio compression format.

File size is typically 50%-70% of the original WAV file.
Widely supported by various music players and streaming services.

Supported input formats:

WAV: Uncompressed audio format
MP3: Lossy compression format (information lost during conversion cannot be recovered)
AAC / M4A: Common format for Apple devices
OGG / Opus: Open-source audio format
WMA: Windows Media Audio format
AIFF: Apple Lossless Audio format
WebM: Web audio format

Compression level descriptions:

0: Fastest compression speed, but larger file size
5: Default level, balances compression ratio and speed
8: Highest compression ratio, but slowest encoding speed
All levels are lossless and do not affect audio quality.
