Compiler error on WebAssembly about audio-engine HOT 7 CLOSED

Oh no, I may have published the wrong branch in crates.io. The wasm-resume branch contains a function to resume the AudioContext in Wasm, but it depends on an unpublished version of cpal (needs this commit).

I will try to yank that version and publish a new one.

But for the time being, you can patch cpal in your Cargo.toml:

[patch.crates-io]

# audio-engine 0.2.2 needs a unpublished version of cpal
cpal = { git = "https://github.com/RustAudio/cpal.git", rev = "b1457e5945cfeb136b7b04c8870b63c2ae3f2212" }

from audio-engine.

Thanks for the answer and suggestion. But if this patch applied I still get the above compiler errors.

from audio-engine.

I published a new version that should solve that error.

But I think that the patch also should have solved the problem. Are you sure that the patch was being applied? It only works if it is put in the Workspace root or in the Cargo.toml of the crate being build (don't work if put in a dependency). You can confirm if it is being applied by running cargo tree, cpal should contain the GitHub address.

But in any case, the new version should solve this. Can you confirm if it works now?

from audio-engine.

Yes, it compiles now. It was my error as you said, did not put the patch into the workspace.

Ok, it compiles now! However I get a crash when I try to decode my wav file.

I will try to narrow it down and also try different wav files. I embed my files use rust_embed.

I get the same error when I play natively on my Mac. Seems to be an unsupported audio sample format ?

from audio-engine.

Seems to be an unsupported audio sample format?

Yes, currently the wave decoder only supports decoding WAV files with a bit depth of 16 bits or lower (the entire audio engine uses i16).

But the engine should at least convert the samples to i16 (and should not panic).

I will close this issue as solved and open a new one for this.

Opened #2
