Track feedback
A free tool at tools.aden.space/feedback. Drop or record a track, through one genre or several (guessed from the track), and read what its low end, balance, drums, sidechain, stereo, key, structure and loudness do, as notes, a map over time, readings against the genre, a mastering chain or the spectrum in 3D, with the tool that fixes each note one press away. Read in the browser.
What it is
Feedback on a track in words, with the picture behind each note. Open
tools.aden.space/feedback, or search "feedback" in ⌘K. No account needed,
and nothing is uploaded.
Using it
- Drop a track, or record it. Record your DAW plays the track through the browser's share picker (tick "Share audio"), so there is nothing to export; Record an input takes an audio interface or a virtual cable.
- It is read in your browser: how its power spreads from sub to air, how the clap, hats and kick sit against each other, how the bass ducks under the kick, how far the hats swing, where the stereo folds in mono, which parts leave the key, where the drops land, and how loud it is.
- The name counts. A genre in the file or version name ("Night Drive (Tech House Mix)") is the guess. An extended or club mix ("Extended Mix", "EXTENDED", "Club Mix") keeps its first and last 16 bars as the DJ intro and outro, never the drop, and gets 32 more bars before its first drop counts as late.
- The genre is otherwise guessed from the tempo, where the backbeat lands, the pump and the balance, and marked Guessed. Pick your own, or several when a track mixes styles (techno and bass house): a reading passes when it is usual in any of them. A genre is a lens, not a rule. Any genre only flags what is off in every genre: clipping, phase and clashing keys. Each genre knows its tempo and where its snare or clap lands (on 3 for dubstep, color bass and future bass; on 2 and 4 for house).
- The waveform sits over every view, drawn like a version's in Aden: press it to play from there, press a part's name (Intro, Drop 1, Break) to jump to it. A tick marks each note's moment, and the open note's stretch is tinted.
- Try the moves. On Range, drag a band's dot on the tone curve (or
use the arrow keys) to try an EQ move; the line follows. You hear the
moves on Range and Master from the start; the other views play the track
as it is. On Master,
each step's diagram has its knobs under it: the high-pass corner, ratio,
attack and reduction for the glue, drive, the clipper, and the push into
the limiter. Turn one and its diagram follows (
stepWith), the limiter's showing where the push lands. Hear the changes (on by default) plays the track through all of it, with its loudness live; switch it off to hear the track as it is. Knobs start where the feedback suggests; double-click one, or Reset, to go back. - Pick the steps you'll do: each master step has a box. Untick one and it dims and drops out of Hear the changes, so you hear only the chain you'll build; tick it again (or turn its knob) to bring it back. Reset ticks every step again.
- Open a step bigger: press a step's drawing for a dialog with it large, its knobs, a play button and its box (untick and tick while it plays to hear it out and in). Tone opens Compare to a reference, the clipper and the limiter open Loudness check, on the same track.
- Press the map (or the 3D view) to move the playhead to that bar.
- Switch views: Notes to read, Map to see where over time, Range to see each reading against the genre, Master for what to put on the master and in which order (clean the lows, shape the tone, glue, width, sheen, clip, limit, each with settings for this track and a small picture of the setting to copy: the filter or EQ curve, the compressor's curve and attack, the width across the spectrum, the limiter's move from where the track sits now), 3D to turn the spectrum over time.
- Add a note of your own in the box under the waveform, like a comment on a version: the clock puts in the time the track is at, Enter adds it.
- Mix score. Beside the genre, "Mix 82%": how close the mix sits to its genres, lower as the notes add up (clipping, phase and clashing keys count more; notes kept as intended don't count). A quick read for sorting demos, not a verdict. Saved demo feedback keeps it, and the inbox card shows it.
- Space plays and pauses. The view and the genres you picked stay in the address, and a refresh opens the last track again with your notes (kept in this browser only).
- Rate a note: thumbs up or down under an open note tells us which notes are right.
- On a version in Aden. A version's … menu, Analyze > Track feedback (or ⌘K, "Track feedback"), opens the same reading on that version's audio. A note's time plays the version from there.
- Save as track keeps your own notes, and a label's, as timestamped comments on the new version.
- From a demo. A label or team that declines your demo can send you its feedback: the link opens here with your demo, the genres they heard it through and their notes. Save as track keeps working on it in Aden. When you sent the demo from a track in Aden, their notes also land on that track as comments, each at its moment.
- Play a note from its moment, open it in the tool that fixes it, or press ✓ to keep it as intended. Kept notes stay one press away.
- The kick, clap, snare and hi-hat tools take their drum from the same song to make a better one. Edit notes opens the stretch in the note editor, to move notes or turn minor into major. The Key finder, Loudness check and Mix vs reference open with the track.
BPM to ms
A free tempo tool at tools.aden.space/tempo. Type, step or tap a tempo, hear it as a click, and copy the length of every note value, straight, dotted and triplet, in milliseconds for delays and pre-delay or in Hz for LFOs.
