Features to Add to the Editor

  • Export audio to WAV with multiple formats
  • Refactor code into multiple files
  • Show Fade In/Out and Crop region times in info panel
  • Detect if file is longer than 174 seconds and show warning if user wants to truncate it or not
  • Drop file to open when no audio is loaded
  • Indicate if file is being processed (loading, truncating, etc.)
  • Drop file to open (when an audio is open) (ask to replace current or append)
  • When appending audio, splice points should be appended to the end of the existing audio
  • Fixed critical loading dialog stuck issue during append operations
  • Drop multiple files to open and create splice points for each file
  • Add/remove splice points to audio using regions
  • Add equal-spaced splice points to audio
  • Play each splice point in the audio with keyboard shortcuts
  • Add splice point locking to avoid accidental deletion and moving
  • Export audio with splice points
  • Transient detection with sensitivity setting and advanced controls (frame size & overlap)
  • Detect zero-crossing on splice points, crop regions, and fade in/out regions
  • Add mobile layout
  • Redo layout so controls are more intuitive
  • Have different fade curves for fade in and fade out (linear, exponential, etc.)
  • Settings menu for:
    • Fade in/out curve type (linear, exponential, etc.)
    • Crossfade lengh and curve type
    • Truncate lenght (174 seconds by default)
    • Default export format
    • Max recording duration
    • Transient detection parameters
  • Add detection preset slots to save sensitivity, frame size, and overlap settings
  • Use mouse scroll to zoom in/out on the waveform
  • Add tooltip to append audio button
  • Detect if audio has more than 300 splice points and show warning if user wants to truncate it or not. Make this number a constant.
  • BPM detection and display it in the info panel
  • Multi-level undo/redo functionality
  • Time stretching and pitch shifting
  • Audio effects (normalization, add/remove gain)
  • Crossfade between splice points with defined length and curve type
  • Record audio directly into the app via Wavesurfer record plugin
  • Reverse audio (applies to whole audio or crop/loop region)
  • Move regions around (crop region) Evaluate better UX, if drag/drop or cut region and paste at the playhead location
  • Audio manipulation via scripting
    • This would be an "expert" mode where users can write scripts to manipulate audio
    • Open a dialog to write scripts and allow importing/exporting scripts (pop from botton)
    • Manipulation applies to whole audio or crop/loop region(rename it?)
    • Maybe add different regions for manipulation
    • Provide modulators like LFO, ADSR to control parameters (in sync or not)
    • Move audio from the regions around
    • API allows fetching and changing audio data (sample based), existing splice points, crop region, and fade in/out regions
    • Multiple tools available with simple API
      • Distortion
      • Add noise
      • Filtering (low-pass, high-pass, band-pass)
      • Reverse
      • Delay
      • Reverb
      • Chorus
      • Flanger
      • Phaser
      • Tremolo
      • Bitcrusher
      • Compressor
      • Equalizer
      • Normalize
      • Time stretch
      • Pitch shift
      • Add fade in/out
      • Add crossfade
      • Add silence
      • Add splice points
      • Remove splice points
      • Lock splice points
      • Remove splice point locks
      • Wavefolding
      • Glitch effects
      • Granular effects
      • Add/remove gain

Bugs

  • Fix bug where splice points are not detected correctly when audio is appended
  • Fix bug where splice points are not correctly placed after the audio is cropped
  • Fix bug where audio files with existing splice markers (cue points) are not being imported/loaded
  • Concatenated audio when cropped, exports as full file and not cropped audio length
  • Contatenated audio when cropped, have splice points duplicated
  • Fix bug where splice markers appear at wrong visual positions after crop operations (while maintaining correct times in export and debug)
  • Locking splice markers are not working after refactor
  • Selecting a locked marker should keep the lock icon visible
  • Truncation seems to not work after refactor
