Hours of live recording, split into songs — no install, just your browser.
Drop in a whole concert. The songs line up automatically; fine-tune the edges by dragging, and send each one onward at its original quality. Nothing is uploaded. What took half a day now takes minutes.
Drop it in, line them up, send them on.
Drop in the whole thing
Even a multi-hour, large file opens as-is. It won’t freeze the way heavy editors do — and nothing is uploaded.
The songs line up
Applause, talking and gaps are told apart, and only the songs are pulled out. The boundaries adjust to each recording, so a quiet recital and a loud concert take the same steps.
Send each one onward
Fine-tune the edges by dragging, and check with the start/end buttons. When it looks right, send that song to the full editor at its original quality — then trim and export as usual.
Tuned to each recording, on its own.
Instead of fixed thresholds, a unique algorithm finds each song’s boundaries from the recording’s own loudness distribution. Different halls, ensembles and set lengths — the same simple steps. It all runs inside your browser; your audio goes nowhere.
Who it’s for.
Students recording their recitals
Record the whole recital, then split it song by song later. No expensive gear, no heavy software.
Recording engineers on live dates
Do the pre-work of cutting songs from one live take right in the browser, and hand them off at original quality.
Whoever archives the band, choir or class
Turn the long recording of a concert or class into tidy, per-song files to share and keep.
After the split, finish it all in one place.
KUON DAR — Digital Audio Restoration & mastering bench
Waveform editing
Zoom, select, trim, silence, five fade curves, and 30 levels of undo.
2-track mixer
Blend two sources with gain, pan, mute, solo and polarity.
Master FX
Graphic EQ, compressor, de-esser, limiter, delay, reverb, stereo width.
Restoration
Noise reduction, click/pop removal, and declipping of distorted peaks.
Analysis meters
Real-time level, spectrum, spectrogram, plus LUFS, True Peak and clipping.
Multi-format export
WAV/MP3 with bit depth, sample rate and metadata, plus TPDF dither at 16-bit. BWF (bext + Coding History) writes the measured LUFS and True Peak into the file itself.
There is more inside DAR.
It is not only a tool for splitting live recordings. Recording, repairing, raising the level, checking and delivering all live on the same screen.
Record in the browser at 32-bit float
Lossless capture of raw PCM. Echo cancellation and auto-gain are switched off so you record the sound as it is. A shadow copy is written inside the browser every second, so a crash still leaves the take recoverable on next launch. Sample drift is checked every 200ms and any dropout is reported with its timestamp.
Hi-res and DSD
Record and edit at 176.4, 192, 352.8 or 384 kHz. WAV files are read natively at their own sample rate and bit depth (16 / 24 / 32-bit integer and 32-bit float). DSD64, DSD128 and DSD256 (.dsf and .dff) open too, converted in 8MB streaming chunks.
Open DAR PRO →A maximizer that cannot exceed the ceiling
A linear-phase FIR splits the signal at 120 Hz and 2 kHz, so dividing the bands does not rotate the phase. Gain is computed from a 1.5 ms lookahead and a moving minimum, which mathematically cannot exceed the ceiling you set. The low band holds for 30 ms to stop sub-bass pumping. Gain reduction is drawn over the waveform, band by band.
Close up the silences automatically
Find the long pauses in a podcast or interview using a threshold derived from the noise floor, then shorten them to a fixed length or cut them out. Joins get a 2 to 30 ms equal-power crossfade. The regions about to go are shown in red on the waveform and update as you move the controls.
The groundwork before you polish
A noise gate, peak / RMS / LUFS normalisation, DC offset removal, left-right balance, and per-region gain (flat or ramped). Load a room profile measured with KUON STAGE and it proposes a corrective EQ and reverberation matched to that room.
Exports that survive delivery
TPDF dither when you drop to 16-bit. BWF export writes bext version 2, iXML and a Coding History, and stamps the measured Integrated LUFS and True Peak into the file itself — a delivery that carries its own measurements rather than a claim that it was processed.
Your saved routine, applied as-is
Save a routine — gain, DC removal, normalisation, fades, maximising — as a patch, then put the next file through the same steps in one click. The export format, the naming template and the QC targets are saved with it, and the pass or fail is shown after export.
Does it meet each platform’s loudness target?
Measure Integrated LUFS and True Peak, then see Pass / Adjust against every major service at a glance — the heart of the former MASTER CHECK, built in.
Hiss, crackle, and clipping — handled.
Sample-based noise reduction, vinyl click removal, and reconstruction of clipped peaks — the former RESTORE / DECLIPPER, unified here.
Your sound stays in your hands.

Frequently asked questions
Can it open large live recordings?
Yes — even multi-hour recordings open as-is. Because nothing is uploaded, there is no waiting.
Does the audio quality drop?
When you send a song onward, it is cut at the recording’s own sample rate and bit depth (for example 96 kHz, 32-bit float).
Is my audio uploaded?
Not automatically. Loading, editing and exporting all happen inside your own browser. Audio is transmitted only when you choose to save it to the cloud.
What if a detected boundary is off?
Drag the edge on the waveform, or nudge the sensitivity. You can also split, merge or delete on the spot.
What happens after the split?
Send each song to the full editor and do the trimming, finishing and WAV/FLAC/MP3 export on the same screen.
What is free, and what is not.
With just an account: single-track waveform editing, import and 32-bit float recording up to 96 kHz, EQ, compressor, limiter and reverb, seven analysis meters, automatic live-recording splitting, WAV/MP3 export, and saving the project to your own device.
The maximizer, advanced restoration, the platform loudness check, automatic silence trimming, pro EQ and reverb, hi-res up to 384 kHz and DSD, a second track, room profiles, and cloud storage.
