问题
I am using Tone.js to modify sounds:
audio_url = "/sounds/damncoolbeats.m4a"
player = new Tone.Player(audio_url)
modified_player = <some Tone.js modifications to player>
To play the modified sound I would like to use a web audio element so that I can make use of audio.currentTime and eventlisteners to 'play' 'pause' and 'timeupdate' (which I can't seem to do with Tone.js).
The only way I managed to create an audio element so far is by loading from an url:
audio = new Audio(audio_url)
My current hacky solution is to load the original url twice, once in Tone.js and once as web audio, then I play both players simultaneously while keeping the web audio volume at zero. Loading the same http resource twice really messes with my website speed though...
Is there a way to create the web audio element from a Tone.js object?
audio = new Audio(modified_player) //does not work
audio = new Audio(modified_player.buffer) //does not work
audio = new Audio(URL.createObjectURL(modified_player.buffer)) //does not work
