Automatic mixing and mastering: a starting point for your song
Mixing decides how the parts of a song sit together. Mastering works on the combined result. Automation can give you a useful first balance, but your ears still decide which performance should lead.
Recording quality comes first
Start with takes you want to keep. A distorted input, noisy room or mistimed performance is easier to address while recording than after the song is assembled. Make a short check with the actual microphone and headphones before a long take.
Headphone cue choices help the performance. Mute and Solo for your headphones determine what guides the next take; they do not replace the decisions in the finished mix.
What the automatic mix does
Mxsie's native engine measures the tracks and makes bounded gain decisions to create an initial balance. The goal is a result you can inspect and iterate on. It is not a trained model that understands every genre, lyric or arrangement.
The broader engine includes filtering, EQ, dynamics and ambience processing, but the Android preview exposes a simpler finishing flow. Do not expect every desktop-style effect control in this first release. Extra instrument and effect controls belong to the planned Full edition.
What mastering changes
The mastering stage works toward a loudness target while respecting a peak ceiling. It creates a new output and measures it again. If the source cannot reach the target within the limits, the engine reports that instead of promising a louder result at any cost.
Judge the result at a similar listening volume to the earlier mix. Louder can feel more impressive even when the balance is worse. Listen for a clear lead, a steady low end and whether the quieter moments still feel intentional.
Keep your takes and export a version
Finishing preserves the original recordings and writes a new render. Keep recording if the song needs another part, then finish another version. An automatic result is a creative checkpoint, not a reason to give up control of the song.
The Android preview exports WAV. MP3, AAC, FLAC and other codec delivery currently belong to the desktop developer companion, not the phone export screen. Save a separate copy of important exports and check the download page for current platform limits.
