Quiet Anvil

AI generated offline dynamics desk with linked compression, detector timing, parallel blend and float WAV output.

Screenshots

Screenshots supplied by the seller.

Description

AI generated. Quiet Anvil is a standalone browser tool for shaping the dynamics of short mono or stereo recordings.

An original stereo linked peak detector drives a hard or soft knee compressor with attack, release, detector high pass and offline lookahead. Input trim, makeup, parallel blend and an optional soft output curve complete the path.

Inspect actual calculated reduction over time and a static transfer curve, loop original or processed audio, save recipes and export the full processed buffer as IEEE float WAV at its decoded sample rate. Three original source programs and four recipes are included.

What works

  • Original stereo linked peak envelope detector
  • Threshold, ratio, soft knee, attack and release controls
  • Detector high pass and offline lookahead
  • Input trim, makeup and parallel blending
  • Optional bounded nonlinear output safety
  • Actual gain reduction graph and static wet transfer view
  • Original and processed loop comparison with monitor headroom scaling
  • Local audio decoder without source normalization
  • IEEE float WAV encoding and recipe JSON files
  • Known level, detector timing and stereo PCM checks

What’s unfinished

  • No microphone or live sidechain input
  • No real time DAW insert, hardware MIDI or native plugin
  • No automatic loudness matching, LUFS or true peak measurement
  • File picker import, completed downloads, recipe round trip and external DAW import are not verified

Technologies

HTML, CSS, JavaScript, Web Audio API

Setup requirements

Open index.html or serve the folder with any static HTTP server. Use a deliberate play action to enable audio.

Dependencies and ongoing costs

No third party libraries, paid APIs or required services. A current Web Audio capable browser is required. Optional static hosting can be free.

Known limitations

AI generated standalone browser file processor. Inputs are mono or stereo, up to 12 MB and 30 seconds with browser dependent codec support. Controls rebuild an offline result; the preview loops that result. Lookahead reads future detector values without adding leading silence. Output safety is a nonlinear curve and can add harmonics. Disabling it can produce out of range float samples. Monitor scaling does not alter export data. Hosted file operations may be restricted.
