Download Formats in Cryo Mix

After processing, you can download your master or mix in four formats:

WAV · MP3 · FLAC · AIFF

Pick the format that matches where the file is going next (distributor, archive, collaborator, social media).

Which Format Should I Upload?

Always upload the highest quality source file you have.

Cryo Mix's AI engine analyzes the frequency content, dynamics, and spatial characteristics of your audio to make processing decisions. The more data the engine has to work with, the better those decisions are.

If you have the original WAV or AIFF from your DAW session, use that. These are lossless, uncompressed formats that give the AI the complete picture.

If you have a FLAC file, upload it directly. FLAC is lossless, meaning it contains the exact same audio data as a WAV, just at roughly half the file size. No need to convert to WAV first.

If you only have a compressed file (MP3, AAC, M4A, or OGG), that's fine. Upload it as-is. Cryo Mix will process it and the results can still sound great, especially for rough demos, quick masters, or projects where the original session files aren't available.

Important: Converting an MP3 to WAV before uploading does not restore the audio data that was removed during compression. The result is a bigger file with the same quality as the original MP3. Always upload the actual original format you have.

Which Format Should I Download?

It depends on what you're doing with the file:

WAV is the standard for music distribution. DistroKid, TuneCore, CD Baby, and most distributors require or strongly prefer WAV uploads. If you're releasing music, download WAV.

FLAC gives you lossless quality at a smaller file size than WAV. Good for archiving your masters, backing up to cloud storage, or sending files to collaborators without the large WAV size. Platforms like Bandcamp, Tidal, and Qobuz also accept FLAC directly.

AIFF is Apple's lossless format. If your post-production workflow runs through Logic Pro, GarageBand, or Final Cut Pro, AIFF keeps things native in the Apple ecosystem. Same audio quality as WAV, different container.

MP3 is best for quick shares, demos, social media previews, and sending tracks to people who just need to hear the song without worrying about file size.

Format Breakdown

Here's a quick overview of each format Cryo Mix supports:

Lossless Formats (no quality loss)

WAV (Waveform Audio File Format) Uncompressed. Full audio quality. Industry standard for recording, mixing, mastering, and distribution. Large file size (roughly 10 MB per minute at CD quality).

AIFF (Audio Interchange File Format) Apple's uncompressed format. Same quality and file size as WAV. Native to Logic Pro, GarageBand, and macOS production tools.

FLAC (Free Lossless Audio Codec) Lossless compression. Identical audio quality to WAV at roughly 50% of the file size. Great for archiving and storage. Supported by Bandcamp, Tidal, Qobuz, and most modern players.

Lossy Formats (smaller file, some quality removed)

MP3 (MPEG Audio Layer III) The most widely supported audio format. Small file size, plays on everything. Quality depends on bit rate (128, 192, 256, 320 kbps). Not ideal for mastering source files, but fine for demos and sharing.

AAC (Advanced Audio Coding) Better audio quality than MP3 at similar bit rates. Common on Apple devices and in streaming. Native format for Apple Music playback.

M4A An AAC file in an MPEG-4 container. This is what your iPhone records voice memos in and what Apple Music uses. Uploads directly to Cryo Mix without conversion.

OGG (Ogg Vorbis) Open-source compressed format. Common in game audio, open-source projects, and certain DAWs. Spotify uses OGG Vorbis for streaming playback.

FAQ

Do all Cryo Mix tools support these formats? Yes. AI Mixing & Mastering, AI Mastering, Beat Optimizer, and Audio Separator all accept WAV, MP3, FLAC, AIFF, M4A, AAC, and OGG uploads.

Is there a file size limit? No. Upload files of any size.

What sample rate and bit depth should I use? For best results, upload at the sample rate and bit depth of your original session. 16-bit or 24-bit at 44.1 kHz or 48 kHz are both great. If you're not sure, 24-bit / 44.1 kHz WAV is the safe default.

Can I upload a video file and extract the audio? No. Cryo Mix only accepts audio files. You'll need to extract the audio from your video file first using a separate tool, then upload the audio file.

Does converting MP3 to WAV improve quality? No. Converting a lossy file to a lossless format does not restore the data removed during compression. It just makes the file bigger. Upload the original format.

Which format do streaming platforms use? Each platform transcodes your upload into its own playback format. Spotify uses OGG Vorbis, Apple Music uses AAC, and Tidal and Qobuz offer FLAC for lossless tiers. You don't need to worry about this. Upload your master in WAV (or FLAC) to your distributor and let the platform handle the rest.
