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

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!

[tar500]

@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>

Comment moved from Issue #54:

Note: I edited my app name to "XXXXXXX" for posting.

When running on my device (iPhone 6s/iOS 12.2), TLSphinx crashes with the following error:

2019-04-16 21:20:22.999246-0400 XXXXXXX[8288:5047903] [aurioc] 1029: failed: -10851 (enable 1, outf< 2 ch, 0 Hz, Float32, non-inter> inf< 2 ch, 0 Hz, Float32, non-inter>) 2019-04-16 21:20:23.023423-0400 XXXXXXX[8288:5047903] [avae] AVAEInternal.h:70:_AVAE_Check: required condition is false: [AVAudioEngineGraph.mm:2037:_Connect: (IsFormatSampleRateAndChannelCountValid(format))] 2019-04-16 21:20:23.023753-0400 XXXXXXX8288:5047903] Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'required condition is false: IsFormatSampleRateAndChannelCountValid(format)' First throw call stack: (0x1bc0d8518 0x1bb2b39f8 0x1bbff2148 0x1c1e99438 0x1c1e98a70 0x1c1ec8de4 0x1c1f40e9c 0x1c1f40f24 0x1049ea91c 0x10239f2ec 0x1023af7b4 0x1023a8e64 0x1023a8ec8 0x1e84d9230 0x1e7f82af8 0x1e7f82e18 0x1e7f81e84 0x1e851029c 0x1e85114c4 0x1e84f1534 0x1e85b77c0 0x1e85b9eec 0x1e85b311c 0x1bc06a2bc 0x1bc06a23c 0x1bc069b24 0x1bc064a60 0x1bc064354 0x1be26479c 0x1e84d7b68 0x1023f7c30 0x1bbb2a8e0) 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?

After copying the code in Decoder.swift to my own project and debugging from there, I found that the crash at Decoder.swift l. 189 can be avoided by changing the AVAudioSession category from .playback to .playAndRecord at l. 173. However, I have no idea how to rebuild the TLSphinx module and incorporate it into my project (see Issue #57). Is there any procedure to do this?

Oh! That's a bug... The category should never be .playback It will be great if you could submit a pull request for that change 😄

I created a pull request, but I'm not sure I did it correctly (this is my first experience with the process).

TLSphinx.Decoder now works successfully in my project. Very responsive and accurate with a small word dictionary. Thank you.

I still need to make changes to Decoder to set the AVAudioSession.Category outside of Decoder (see Issue #57).
