i want to use LSTM based audio network to work with Live audio
28 views (last 30 days)
Hello Matlab team,
I am using this example to work with my audio data set https://www.mathworks.com/matlabcentral/fileexchange/74611-fault-detection-using-deep-learning-classification#examples_tab dataset is trained but I want to make the application live with PC, forexample I have a mic and make an application to use my trained model to predict the output.
Can you guide me or help me with that?

There is a function in that repo (streamingClassifier) that should get the job done in conjunction with an audio device reader:
% Create a microphone object
adr = audioDeviceReader(SampleRate=16e3,SamplesPerFrame=512);
% These statistic value should come from your training...
M = 0;
S = 1;
% Read a frame of data from microphone
frame = adr();
% Pass to network
scores = streamingClassifier(frame,M,S);
% Use the scores any way you want

audioDeviceReader supports multi-mic devices. Use the ChannelMappingSource and ChannelMapping properties to map between device input channels and the output data.
This network was trained on mono data, so, to adapt it to multi-channel data, you either have to retrain your network for multi-channel data, or somehow combine your input channels into one channel (by a weighted sum, or selecting a particular channel, etc) and proceed like above.
