javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 44100.0 Hz, 8 bit, mono, 1 bytes/frame, not supported.

It appears that your device does not support 8 bit mono recording.

It appears that your device does not support 8 bit mono recording.

i change to 16 again error.

Which device / OS are you using?

Are you loading multiple files?

i

Which device / OS are you using?

Are you loading multiple files?

i run on windows 10.
i just run jAudiorecordNonUI sample.

 

[stevel05]

Got to ask the obvious questions: Does your PC have a sound card?
Is it in use by any other software?

i have laptop.
with jetaudio i can record mic and play sound.
in Vb.net also can record mic.
no not in use by other software.

 

[stevel05]

OK, the example is just that. It depends on your computer having a a device called "Primary Sound Capture Driver".

Run this code separately, you will then see which devices are available on your computer, pick one that looks like the generic / mic input and update the CaptureDevice string.

Dim AudioSystem As JavaObject
AudioSystem.InitializeStatic("javax.sound.sampled.AudioSystem")
Dim MixerInfo() As Object = AudioSystem.RunMethod("getMixerInfo",Null)
For Each MI As JavaObject In MixerInfo
    Log(MI.RunMethod("getName",Null))
Next

Or change Appstart to:

AppStart (Args() As String)
    'Default dataline
    RecordFile1.Initialize(Me,"RecordFile1")
    
    Dim AudioSystem As JavaObject
    AudioSystem.InitializeStatic("javax.sound.sampled.AudioSystem")
    AudioFormat.InitializeNewInstance("javax.sound.sampled.AudioFormat",Array(SampleRateHz,SampleSizeInBits,ChannelConfig, True, False))
    InDevice = AudioSystem.RunMethod("getTargetDataLine",Array(AudioFormat))
    
    
    Dim TDL As TargetDataLineWrapper
    TDL.Initialize(InDevice)
    TDL.AddLineListener(Me,"DataLine")
    
    If RecordFile1.IsInitialized Then
        If RecordFile1.IsRecording Then
            RecordFile1.Stop
        End If
    End If
    If File.Exists(FilePath, FileName) Then File.Delete(FilePath, FileName)
    RecordFile1.Start(TDL, File.Combine(FilePath, FileName))
    
    StartMessageLoop

To record the system default input

i used code and change CaptureDevice.

i set Microphone (Conexant SmartAudio for MI.
an this log appear.

Are you trying to run in debug mode? The threading library runs in Release mode only.
