# runtime/cgo
cgo: unknown ptrSize for $GOARCH "wasm"

You almost certainly want the original opus C library, not this thin Go <-> C wrapper. I don't know wasm but I did opus in asm.js once upon a time and this library (hraban/opus) was only useful on the server side, where I used Go. On the client I used asm.js, so I had to compile the original C library using emscripten. I'm assuming it will be similar for wasm.

Feel free to reopen with more info & context if you think I misunderstood the state of wasm
