Hi,
I am using SVM to train and clasify the audio files based upon extracting the MFCC and PLP features for 10 audio files And store it in a .mat file. I have to classify depending upon the high pass filter, low pass filter,etc...
I am new to SVM I have to train some of the audio files and test the data (different) later on so I am bit confused what to do next? I have to store the features data in .mat file and input that as the training matrix?
Thanks in advance

  • What have you tried so far?
  • what is the format of the audio files?
  • If you are looking for MATLAB functions for train and test, "svmtrain" and "svmclassify" are the functions.
  • If you are looking for functions related to audio, refer to this link

Rajith,
For training, use "svmtrain" function. Here is the documentation page for "svmtrain". Note that in the documentation, input argument "Group" is where you can mention the class labels - high pass filter, low pass filter,etc and "Training" is your training data.
You can find few examples on SVM here
