Frequently Asked Questions
Will converting MKV to FLAC reduce audio quality?
No, FLAC is a lossless format that preserves 100% of the original audio quality from your MKV file. The conversion extracts the audio stream and compresses it without any quality loss, maintaining the original bit depth and sample rate.
Can I extract multiple audio tracks from a single MKV file?
Yes, MKV files often contain multiple audio tracks (different languages, commentary, etc.). Convertify can identify and extract specific audio streams, allowing you to choose which track to convert to FLAC format.
What audio codecs in MKV files are supported for FLAC conversion?
Convertify supports all major audio codecs found in MKV containers, including AC-3, DTS, DTS-HD, TrueHD, PCM, AAC, MP3, and Vorbis. The software automatically detects and processes the audio stream regardless of the original codec.
How much smaller will my files be after converting to FLAC?
FLAC typically reduces file size by 30-50% compared to uncompressed audio while maintaining perfect quality. The exact compression ratio depends on the audio content – music with more complexity compresses less than simpler audio.
Will metadata like title and artist be preserved during conversion?
Yes, Convertify automatically transfers available metadata from the MKV file to the FLAC output, including title, artist, album, and other tags. The software converts metadata to FLAC-compatible formats for maximum compatibility.
Can I convert very large MKV files without running out of memory?
Absolutely. Convertify uses intelligent streaming processing that handles files of any size without loading the entire file into memory. This allows conversion of multi-gigabyte MKV files even on systems with limited RAM.
What sample rates and bit depths are supported in the conversion?
Convertify preserves the original sample rate and bit depth from your MKV audio stream, supporting rates up to 192kHz and bit depths up to 32-bit. The FLAC output will match the source audio specifications exactly.
