01 · LOAD
Open the stereo mix
Sunset decodes the file locally, measures the starting level and keeps the source available for before/after listening.
MASTERING · STEREO MIX TO RELEASE
Finish the record.
Bring a finished stereo mix. Sunset measures it, shapes tone and dynamics toward a reference or target, controls loudness and true peak, then exports the master with the evidence needed to check delivery.
What goes in
A finished stereo mix in WAV, AIFF, MP3 or FLAC. If you still need to rebalance individual instruments, start in Mixing with stems before mastering.
THE WORKFLOW
From approved mix to release master.
Choose a creative target, run the chain, compare fairly and export for the actual destination.
02 · TARGET
Choose the destination
Load a reference track, use saved Reference DNA, choose a genre target and set streaming or club intent.
03 · PROCESS
Run the release chain
Corrective tone, multiband dynamics, stereo image, saturation, loudness control, true-peak limiting and dither run in order.
04 · COMPARE
A/B at equal loudness
Compare source and master without the louder-is-better trick. Inspect spectrum, loudness, peak, width and dynamics.
05 · VERIFY
Check translation
Review platform readouts, mono and codec-risk checks, low-end behavior and the plain-English Audio Doctor findings.
06 · DELIVER
Export audio and proof
Choose format, bit depth and sample rate, then save the master, report card or release proof bundle.
MASTERING TOOLSET
Creative target in. Measured delivery out.
Reference matchingReference DNA captures third-octave tonal balance, integrated loudness and stereo width for repeatable matching.
Genre & platform targetsStarting targets for electronic and contemporary styles, with explicit LUFS and true-peak destination settings.
Signal chainHigh-pass cleanup, corrective EQ, five-band glue, stereo imaging, parallel saturation, loudness normalization, true-peak limiting and dither.
MeteringITU-R BS.1770 loudness, 4× oversampled true peak, short-term loudness, correlation, width and dynamic-range views.
Quality controlEqual-loudness A/B, Audio Doctor, low-end and mono checks, AAC artifact preview, delivery variants and explainable notes.
ExportWAV or AIFF PCM, AAC in M4A, and lossless FLAC with selectable 16/24-bit depth and sample-rate conversion where supported.
DELIVERY, NOT GUESSWORK
Keep the master and its proof together.
Sunset can export a plain-text or JSON proof report, a shareable report-card image and a release bundle alongside the audio. MP3 export is intentionally not offered because no licensed MP3 encoder ships in the app; AAC is the real lossy encode path.
