13.8.25

• Moving to common.js-style code

Breaking Changes

• AudioNode.prototype.connect is no longer overwritten. This means that you can no longer connect native nodes to Tone.js Nodes.
• Tone.connect(srcNode, destNode, [ouputNum], [inputNum]) is the way to connect native Web Audio nodes with Tone.js nodes.

13.4.9

• Updating semantic versioning to be more in line with other semvers. Now version is 13.x.x
• logging full version
• Added Object notation for Tone.TimeBase and classes that extend it.
  • i.e. Tone.Time({'4n' : 1, '8t' : 2})
  • Replacement for deprecated expression strings.
• Tone.Meter uses RMS instead of peak (thanks @Idicious)
• Tone.Sampler supports polyphonic syntax (thanks @zfan40)
• Building files with webpack
• Follower/Gate uses a single "smoothing" value instead of separate attacks and releases
• Changing references to window allowing it to not throw error in node context
• Testing examples
• Tone.Channel combines Tone.PanVol with Tone.Solo.
• Removing require.html example.
• adding partialCount and baseType to Oscillator classes, helps with getting/setting complex types.
• New examples with updated interface
• Tone.start() to simplify resuming the AudioContext

r12

• Consolidating all shims into shim folder
• Using ConstantSourceNode in Signal when available
• switching to eslint from jshint
• Running CI tests on Firefox, Chrome (latest and canary) and Safari (latest and version 9).
• Tone.Reverb is a convolution-based stereo reverb. Example.
• Optimizing basic Oscillator types and many Signal use-case
• Optimizing basic connection use-case of Tone.Signal where one signal is controlling another signal
• Testing rendered output against an existing audio file for continuity and consistency
• Optimizing triggerAttack/Release by starting/stopping oscillators when not playing
• TickSource (used in Clock and Player) tracks the elapsed ticks
  • Improved precision of tracking ticks in Transport and Clock
• Player.position returns the playback position of the AudioBuffer accounting for any playbackRate changes
• Removing retrigger option with Tone.Player. Tone.BufferSource should be used if retriggering is desired.

BREAKING CHANGES:

• Tone.TimeBase and all classes that extend it not longer support string expressions.
  RATIONALE :
  * Since all classes implement valueOf, expressions can be composed in JS instead of as strings
  * e.g. Time('4n') * 2 + Time('3t') instead of Time('4n * 2 + 3t')
  * this change greatly simplifies the code and is more performant

r11

r8

Better Source syncing to the transport, 3D Audio Spatialization and temporary fix for bug in Chrome 53+.

CHANGELOG:

• Transport.seconds returns the progress in seconds.
• Buffer.from/toArray, Float32Array <-> Buffer conversions
• Buffer.slice(start, end) slices and returns a subsection of the Buffer
• Source.sync now syncs all subsequent calls to start and stop to the TransportTime instead of the AudioContext time.
  • e.g. source.sync().start(0).stop(0.8); //plays source between 0 and 0.8 of the Transport
• Transport.on("start" / "stop") callbacks are invoked just before the event.
• Param can accept an LFO description in the constructor or .value
  • e.g. param.value = {min : 10, max : 20, frequency : 0.4}
• Time.TimeBase has clone/copy methods.
• Tone.Buffer.prototype.load returns Promise
• Using Tone.Delay and Tone.Gain everywhere
• Patch for Chrome 53+ issue of not correctly scheduling AudioParams with setValueAtTime

r6

Big changes are the new event classes: Tone.Event, Tone.Loop, Tone.Part, Tone.Sequence, and Tone.Pattern. These simplify interacting with the Transport.schedule (formerly Transport.setTimeline). They allow you to more easily schedule loopable, schedulable, and modifiable events along the Transport's timeline.

All Changes:

• Added PitchShift and Vibrato Effect.
• Added Timeline/TimelineState/TimelineSignal which keeps track of all scheduled state changes.
• Clock uses requestAnimationFrame instead of ScriptProcessorNode
• Removed onended event from Tone.Source
• Refactored tests into individual files.
• Renamed some Signal methods: exponentialRampToValueNow->exponentialRampToValue, setCurrentValueNow->setRampPoint
• LFO no longer starts at bottom of cycle. Starts at whatever phase it's set at.
• Transport is an event emitter. triggers events on "start", "stop", "pause", and "loop".
• Oscillator accepts a "partials" array.
• Microphone inherits from ExternalInput which is generalized for different inputs.
• New scheduling methods on Transport - schedule, scheduleOnce, and scheduleRepeat.
• Tone.Gain and Tone.Delay classes wrap the native Web Audio nodes.
• Moved MidiToScore and TypeScript definitions to separate repos.
• Tone.Param wraps the native AudioParam and allows for unit conversion.
• Quantization with Transport.quantize and using "@" in any Time. Read more.
• Control-rate generators for value interpolation, patterns, random numbers, and markov chains.
• Scheduable musical events: Tone.Event, Tone.Loop, Tone.Part, Tone.Pattern, Tone.Sequence.
• Player's playbackRate is now a signal and Noise includes a playbackRate signal.
• All filterEnvelopes use new Tone.FrequencyEnvelope with frequency units and baseFrequency and octaves instead of min and max.
• Phaser uses "octaves" instead of "depth" to be more consistent across the whole Tone.js API.
• Presets now have their own repo

DEPRECATED:

• setTimeout, setInterval, setTimeline in favor of new schedule, scheduleOnce, and scheduleRepeat.
• Tone.Signal no longer takes an AudioParam in the first argument. Use Tone.Param instead.
• Tone.Buffer.onload/onprogress/onerror is deprecated. Use Tone.Buffer.on("load", callback) instead.
