It provides advanced scheduling capabilities, synths and effects, and intuitive musical abstractions built on top of the Web Audio API. Synth is a basic synthesizer with a single envelope and single oscillator. The second argument is the duration that the note is held. This value can either be in seconds, or as a tempo-relative value. The third optional argument is when the note should be scheduled to play.
With no argument, the note plays immediately, but it can also be scheduled to play anytime in the future. Web Audio has advanced, sample accurate scheduling capabilities. The AudioContext time, which is the reference clock that Web Audio uses to schedule events, starts at 0 when the page or iframe loads and counts up in seconds.
The third argument of triggerAttackRelease is when along the AudioContext time the note should play. It can be used to schedule events in the future. Instead of defining all values in seconds, any method which takes time as an argument can accept a number or a string. For example "4n" is a quarter-note, "8t" is an eighth-note triplet, and "1m" is one measure.
Loop is a simple way to create a looped callback that can be scheduled to start, stop and repeat along the Tone. Part allows you to schedule an array of events which can be started, stopped, and looped along the Transport. All of the Tone. This can create some interesting phasing.
The synths and effects are capable of a diverse range of sounds. All instruments are monophonic one voice but can be made polyphonic when the constructor is passed in as the second argument to Tone. PolySynth creates multiple instances of an instrument and manages the voice allocations. In the above examples, the synthesizer was always connected directly to the master outputbut the output of the synth could also be routed through one or more effects before going to the speakers.
Tone has a few basic audio sources like Tone. Oscillator which has sine, square, triangle, and sawtooth waveforms, a buffer player Tone. Playera noise generator Tone. Noisea few additional oscillator types pwmpulsefatfm and external audio input when WebRTC is supported. This is a powerful feature which allows for sample-accurate synchronization and scheduling of parameters. More resources can be found on the github pageforumwikiand demos.BSD licensed.

It also serves a consistent html player UI to all browsers which can be styled used standard css. It plays mp3s. No ogg. Because, lets be honest, in the real world, no one really exports ogg files. Sadly, that means Opera and Firefox get flash audio.
Hopefully they can add mp3 support soon. Put audio. On OSX, you should install closure compiler following the instructions in Ben's gist.

Audio files are automatically cached where possible to improve playback performance. A significant challenge with audio is supporting codecs. The specification has been under steady change for more than five years, with several rounds of deprecations of crucial features.
Recent work moves the audio processing to a separate thread similar to web workers with AudioWorklets. Browser support for Web Audio remains inconsistent, and Howler. The most recent challenge is the introduction of r equiring user interaction before an audio clip may playwithout a mechanism to approve auto-play for specific websites. Web audio is like Canvas for sound, giving that low level access to sound. Following that logic, Howler. Maybe once web audio is fully adopted, we'll see Instagram-like filters start to show up for audio!
Several large technology and media companies leverage Howler. Contributions are welcome via the Howler. Enhance your end-user experience by optimizing your application performance. Get a holistic view of your application behavior with Site24x7. Join a community of oversenior developers.
Which of the following libraries come recommended and for what purposes? What can I expect in terms of documentation and support eg: is that library likely here to stay? I don't need UI features for my needs and would rather keep things small and simple.
I mainly wanna save myself the need to try out all those libraries and more to figureout their pro's and con's. You may have already selected a library, but as the developer of howler. From your description, I'd say howler.
It is great for both simple and complex tasks, and leaves any UI needs up to the developer. It allows you to get audio up and running with minimal code that will work across all modern browsers.
Looping and playing from an offset both work smoothly. As far as I know, looping only a slice of a larger audio file smoothly can only be done with pure web audio, which currently is only supported in Chrome and Safari.
SoundJS doesn't support that functionality directly, but does allow you access the web audio nodes directly so you can set it up manually. It provides a simple API to create and play sounds.
