14.5.1 Introduction

We provide six samples for acoustic feature extraction (See Table 14.12) The leftmost column indicates the sample network file names, and the rest columns indicate the whether the feature include the information or not. All the files work in offline, if you want to extract feature in online, replace AudioStreamFromWave with AudioStreamFromMic . If you want to use MFCC instead of MSLS, replace MSLSExtraction with MFCCExtraction .
