No audio?

Hi,

I'm not getting any sound with the default session in Chrome after inserting a slice into the canvas and pressing play. Is there something else I'm supposed to do to hear audio?

Hello,

this should work, what is your GPU/CPU/hardware ? Do you use the launcher ?

Try to unpause in this session : https://www.fsynth.com/app/webgl1

Yep it works, though with crackles. I'm on a GTX 760, i7 920, RME Babyface, all on Windows 10. I'm not using the launcher.

(Currently on Chrome 63.0.3239.108)

Ah, default session works now too (with crackles).

fsynth

Make sure you don't have "wavetable" checked when you open the settings dialog (gears icon)

Also, the only solution to prevent crackles with web-only audio is to reduce the canvas score height in the settings dialog (try something like 200px or less, lowering the polyphonic/note lifetime settings can help as well)

Some settings such as show globalTime/show osc infos may also affect the amount of crackles.

Sadly, web-audio only will stay with more than high requirement for some time until some new features of the Web Audio API are released (might come in 2018/2019)

The alternative solution (which work best and make use of your audio interface) is to use the audio server/launcher.

fsynth Ah interesting, that works. thanks!

Hi, sorry for reviving that old thread.. :-P
I have the same problem, but tried the test patch above and I still have no sound. I've tried both with the online audio engine and the local audio server. I tried all the audio outputs in the list in the local server, and tested with Brave, Chrome and Chromium browsers, and still the same issue. My MIDI keyboard works, and I can see the notes I play in the visualizer, but I have no audio.
GPU is a GTX 1080 and CPU is a Ryzen 3700X. I'm running the latest version of Windows 10, but I know someone on Linux that has the same problem.
Anything I could try to fix this?
Thank you!

Hello,

you can try to change the score height in the settings dialog, this fixed the issue for me under Chrome. The version that is online is quite old and this bug may be related to Web Audio waiting an user action to resume the audio context.

There is no reasons the audio server won't work though, did you connect the client to the server by using the waveform icon ? You should see three green icons on top left of the screen when it is connected.

Hello,
OK, I tried with the online version only in Brave and changed the score height a couple of times. Still nothing.
As for the audio server, I did connect the client to the server properly and it showed the 3 green icons.

fsynth

Odd, did you tried with a fresh session ? Did you also click on the pause toggle button to unpause the audio ? (the blue/green toolbar button)

Just tried with Brave after a fresh install and it worked.

VincyZed

Sorry for the very late reply!
I've just tested with a fresh session, unpaused the audio and there is still nothing. I should hear a tone on that default session, right?
It's odd that it works on your side but nothing for me at all..

Just an update in case : The 2.0 version should work now.
