Track Overview
Stereo field
Whole-track overviewSelect an audio file to see its stereo field. Saved measurements alone cannot recreate this image.
How to read this image
A narrow vertical image indicates similar channels. A wider cloud shows more stereo difference; points beyond the L/R diagonals can indicate phase cancellation. Listen in mono as well. Sampled across the track, with a shared visual gain for both axes.
Waveform
Drawn locally in your browser from the file you selected — not sent anywhere to render this.
Frequency Balance
Energy per band, averaged across the whole track (not a single instantaneous snapshot) — Sub 20–60Hz, Bass 60–120Hz, Low Mids 120–500Hz, Mids 500Hz–2kHz, Upper Mids 2–6kHz, Highs 6–20kHz.
Average frequency spectrum
Reanalyze your track to generate its spectrum.
How to read the spectrum
Time-averaged FFT power across both channels. Frequency runs logarithmically from 20 Hz to 20 kHz; 0 dB is this curve’s highest point, not absolute loudness. Bass, midrange and high-frequency peaks show tonal balance. This does not diagnose masking between instruments or guarantee mix quality.
What this means
A note on what this is: these are measurements, and the explanations above only describe what was actually measured — nothing here is invented or guessed. Automated mastering (below) is a fast, measurement-driven starting point; it's not a substitute for a mastering engineer's judgment, and we don't market it as one.
Mastering
€9.99 per master (1 credit if you pay with credits), one price for any profile below. Select a profile, then enter your email and continue to payment.
Balanced
Preserves dynamics and character. A gentle, transparent master for genres where dynamic range matters as much as loudness.
Loud Electronic
Higher perceived loudness within bounded, measured limits — for electronic and dance material where competitive loudness is part of the sound.
Streaming
Controlled loudness and true-peak headroom as a mastering preference, not a platform requirement — streaming services don't mandate one exact LUFS target.
