Can't record sound on Windows #40

Closed ArtyCake closed 5 years ago

ArtyCake commented 7 years ago

I've installed binaries and updated PATH variable I'm using node-record-lpcm16 with @google-cloud/speech for speech recognition. But when i run record i've received next to console: 

Recording with sample rate 16000...  
Recording 4163 bytes  
Recording 1385 bytes  
End Recording: 76.632080078125ms

That's all. It doesn't depend on what stream i'm using speech.createRecognizeStream from google or simple fs.createWriteStream

My settings are 

record
  .start({
    sampleRateHertz: 16000,
    threshold: 0.1,
    verbose: true,
    recordProgram: isWin ? 'sox' : 'rec',
    silence: '1.0',
  })

rec causes spawn rec ENOENT on windows sox on mac causes same behavior 

Recording with sample rate 16000...
Recording 5344 bytes
End Recording: 12.887939453125ms

But with rec it work as expected. Recognition works fine

I'm getting the same error, but everytime I use it, it records in total exactly 5548 bytes.

I'm getting the same error. With sox, it records in total exactly 5548 bytes and then stop recording. With rec I got "spawn rec ENOENT" on windows.

Also not working on windows 7 for me. Node version 8.11.2, npm version 5.6.0

gillesdemey commented 6 years ago

Can you verify if this bug still occurs with v0.3.1? :)

AkaiBF commented 6 years ago

I can't see the "Recording X bytes" message now, but still stops working at around 160ms.

qunliu commented 6 years ago

I tried the latest v0.3.1 on both macos and Windows, same issue. They all start then end very soon (eg: End Recording: 20 ms or so). I tried recordProgram using 'sox' on Windows, 'sox' and 'rec' on macos, no difference. Any clue?

Use rec on Mac OSX and sox on Windows 10.

On Windows 10, the current sox config results in corrupt files/streams (this is a sox + Windows 10 bug I assume). The following settings circumvent this: sox -t waveaudio default -b 16 -c 1 -e signed-integer -r 16000 --endian little -t wav - > voice.wav More about this here.

I also found that when buidling Electron apps on Mac the $PATH settings are not properly passed anymore. The NPM fix-path module solves this problem.

@bsluis the command you provided sox -t waveaudio default -b 16 -c 1 -e signed-integer -r 16000 --endian little -t wav - > voice.wav works fine. But I can't get node-record-lpcm16 to work. I receive the following console output and empty wav file:

Recording 1 channels with sample rate 16000...
