LineUnavailableException

[EricZeiberg]

Whenever I try to run mic.captureAudioToFile, it gives me a javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported error

Here's my code - https://gist.github.com/MasterEjay/11126602

You need to close the microphone before you reopen it. The issue comes from the fact that you keep trying to run the code over and over again with only one if statement terminating in the mic.close() being called. I've forked the gist, but I do not know how to submit a pull request so just check out my fork to solve the issue.

Its still throwing the line with format PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported error.

Yes, my computer does have a microphone. I was trying the api out before,
and it did correctly get what I said. So, its definitely getting my mic.
The error only happens when I speak above the threshold.

Does your computer even have a microphone? If it does, look up what audio
formats it supports and override the getAudioFormat() method in microphone.

Sigh, can't a guy go on vacation. Anyway to the point, you need to close the microphone before writing to a second audio file as is the case with filename1. Microphone can only write to one file at a time. If you are just using the microphone to detect volume, use mic.open() instead of mic.captureAudioToFile(String). Mic.open() allows you to get metrics such as volume while allowing the targetdataline to be available.

Ok, I'll try that when I get home. Thanks :)

Sigh, the price of maintaining an on-fire GitHub repo.

Still throwing the same error, heres my class - https://gist.github.com/MasterEjay/11267714

[Skylion007]

Now you are using two microphone objects? That will cause an error as well.
Just reuse the MicrophoneAnalyzer class, it extends the Microphone class.
Your setup is unnecessarily complicated. The microphone class assumes
control of the TargetDataLine which directly controls the entire
microphone. Try reducing it to one Microphone class. Unfortunately,
TargetDataLine requires that it has full control over the hardware in
question. For this reason, you cannot call two TargetDataLines at the same
time.

Really sorry to keep pestering you about this, but its still giving me the error. https://gist.github.com/MasterEjay/11274633

[Skylion007]

Sorry about that, I just was able to reproduce the bug and just committed a patch. Sorry, it was a regression in one of the newer versions of the API. Thank you so much for the information.

[EricZeiberg]

Arrg, still not working for me. I grabbed your code changes to Microphone class and built my own version.
