Lambda Musika TODO

Milestones

0.1.x

  • [BUG] [PLAYER] TimeSeeker maxes at 23:59 (HH:MM)
  • [FEATURE] [EDITOR] Save as (allow right-click save-as on save button?)
  • [FEATURE] [EDITOR] Hotkeys for time seeking
  • [FEATURE] [SCRIPTS] Use strict mode?

0.2.0

  • [FEATURE] [API] [PLAYER] [RENDERER] Musika scripts with Mono output
  • [FEATURE] [PLAYER] Volume slider
  • [FEATURE] [COSMETIC] [PLAYER] VU meter

0.2.x

  • [FEATURE] [RENDERER] Quantization
    • More quantization methods (currently truncating)
    • Dithering
    • Clamping?
  • [FEATURE] [RENDERER] Float PCM output
  • [FEATURE] [RENDERER] Select bit-depth etc. when rendering
  • [?] [RENDERER] Handle big/little endian architectures (I don't remember what I meant with this task)

0.3.0

  • [API] [MUSIKA] popping_wip example was bugged: since you can seek time, t is non-monotonic, which made the state invalid. Is this a flaw of the API? Should the user not assume t is monotonic? Maybe some kind of events?

    Another instance: biquad filters became unstable because of t not being monotonic.

  • [API] [MUSIKA] [MUSIKA-UTIL] Log-to-Linear function and viceversa (for linear parameters into freqs and such)

    • Also for amplitude? I.e. work with decibels

  • [API] [MUSIKA] [MUSIKA-ENVELOPE] More interpolations for Attack/release envelopes

    • Linear
    • Hermite

  • [API] [MUSIKA] [MUSIKA-ENVELOPE] ADSR Envelope

  • [API] [MUSIKA] [MUSIKA-ENVELOPE] Should inv envelopes actually be logarithmic?

  • [API] [MUSIKA] [MUSIKA-MUSIC] Chordify signals (given an osc constructor, instance several and mix)

  • [API] [MUSIKA] [MUSIKA-MUSIC] Randomization helpers

  • [API] [MUSIKA] [MUSIKA-MUSIC] Timing helpers

  • [API] [MUSIKA] [MUSIKA-MUSIC] Compositional helpers

  • [API] [MUSIKA] [MUSIKA-MUSIC] Arpeggiator

  • [API] [MUSIKA] [MUSIKA-UTIL] Memoization helper

  • [API] [MUSIKA] [MUSIKA-UTIL] Rate limiting helper (e.g. for control rates)

1.0.0

  • [BUG] [PLAYER] Sound clicks on play/pause/update/seek
  • [FEATURE] [COSMETIC] [APP] Some kind of help/README/intro/tutorial
  • [FEATURE] [COSMETIC] [EDITOR] Visual feedback after commit (annotation?)
  • [COSMETIC] [APP] Favicon(s)
  • [TODO] [MUSIKA] Documentation
    • Add missing comments
    • Static documentation generation

1.0.x

2.0.0

  • [API] [PLAYER] [RENDERER] Using t as DSP time variable is awkward
    • Abstraction is leaking everywhere (e.g. filters don't work with time, only samples)
    • Possible solution: work with samples and dt instead
    • Problem: t is still useful in other situations (e.g. envelopes)

  • [COSMETIC] [PLAYER] https://reactify.github.io/react-player-controls/
  • [COSMETIC] [EDITOR] Custom scrollbars (ajaxorg/ace#869)
  • [FEATURE] [EDITOR] History state might have low storage limits, fall back to localStorage with large files?
    • Maybe limit undo length too?
  • [FEATURE] [EDITOR] REPL
  • [FEATURE] [EDITOR] Save/load code from Gist (+ link generation)
  • [FEATURE] [EDITOR] Work as a git repository, maybe even link with GitHub

    • Function calls might be expensive, leave it to the user?
  • [API] [MUSIKA] Maybe use object options instead of parameters (for easier composition of functions)
    • Objects might be expensive, leave it to the user?

  • [RESEARCH] Ring modulation
