So, this is my output and a crash.... upon my app starting I call startDecoding speech...
how can I get specific outputs in an organized way ???? help

[nshmyrev]

Also asked at

http://stackoverflow.com/questions/39088320/tlsphinx-audio-recognition-issues-in-swift

Resolved. I had to change the CHANNEL to 2 instead of 1.

[nshmyrev]

I had another similar report recently, basically it crashes with

* Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: IsFormatSampleRateAndChannelCountValid(outputHWFormat)'

The offensive line is, once removed it works better https://github.com/tryolabs/TLSphinx/blob/master/TLSphinx/Decoder.swift#L203

[cgamache]

@Qwill ... Tried 2 for channels, same error with my iPhone 6s ...
@nshmyrev ... Removed the referenced line, no good there either.

I did some digging and whereas I couldn't find a true smoking gun, some Apple docs indicate in a footnote that iPhone 6s does not support a sample rate of 44100... It does support 48000. But even with that change, I still get errors:

ERROR: [0x1b20cac40] >avae> AVAudioIONodeImpl.mm:884: SetOutputFormat: required condition is false: format.sampleRate == hwFormat.sampleRate

And I've been digging around trying to find a way to get those to match-up. Any clues or assistance would be very welcome!

@cgamache Same issue with another project using AVAudioEngine: required condition is false: format.sampleRate == hwFormat.sampleRate
It works all the time, but start to fail when a special song is added to an unrelated AVAudioMix and played back via AVPlayer. It is blowing my mind, just a magic.
Apple developer forums have a related thread, where Apple Staff confirm similar bugs existence https://forums.developer.apple.com/message/36184#36184

I'm really close to give up and get rid of AVAudioEngine in my project :(

[cgamache]

A quick update. My latest experiments attempting to fix this issue revolve around injecting a mixer node between the input and output nodes to alleviate the mismatches. No luck so far, but the AVAudioEngine documentation is less-than-exhaustive and there are plenty of permutations to try.

[nshmyrev]

Well, pocketsphinx can process stereo 48k, no issues. You need to add -nfft 2048 -samprate 48000. We can also introduce a resampler.

[revolter]

I am having the same crash though I don't use this library. I got these days 8 crashes on iPhone 6s Plus and one on iPhone 6s, but when testing locally on an iPhone 6s, I get no crash. This is the audio format:

<AVAudioFormat 0x170480000:  1 ch,  44100 Hz, Float32>

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)

However, it runs as expected on the simulator (same hardware/iOS). I single-stepped and found that the error is thrown at line 189 of Decoder.swift:

"engine.connect(input, to: mixer, format: input.outputFormat(forBus: 0))"

Nothing in the code looks amiss.

Is there a workaround available?
