```val channel = Channel<ByteArray>(capacity = 10 ...

# coroutines

val channel = Channel<ByteArray>(capacity = 10 <---------, onBufferOverflow = DROP_OLDEST)
launch {
    while (isActive) {
        val bytes = queryMicrophone()
        channel.send(bytes)
    }
    channel.close()
}

How can I tweak the capacity empiraclly what effectively is a ring buffer?

I.e. I need to analyze if the overflow behavior happened, which is undesirable in my case. (It can happen but should not for ideal UX => increase buffer size)

is there some sort of channel.isFull I can check before `send`ing?

By tweaking it empirically, do you mean at runtime? Or do you mean you'll do some testing and figure out how often the buffer is full?

[Youssef Shoaib [MOD]]

There is a onUndeliveredElement parameter that should help with your testing. It's called on every dropped element I believe, so you can count how often that happens and adjust the size accordingly

yes only for testing purposes, for the capacity to not be a total gut feeling

I see, thanks!
