Spectro is a freeware audio file analyzer for windows. Currently capable of reading FLAC, APE, MP3 and WAV files. Spectro lets you view vital data about compressed audio files and creates a spectrogram of the wave data. This allows you to quickly and easily spot quality issues with a file and also look for transcodes.

It contains 8,732 labelled sound clips (4 seconds each) from ten classes: air conditioner, car horn, children playing, dog bark, drilling, engine idling, gunshot, jackhammer, siren, and street music.

So if you calculate the spectrogram of the result, you should get the result you're after. After all, the spectrogram and the waveform are two different interpretations of the same information and this allows you to do the subtraction at one form and convert to the other.

Jun 25, 2015 · The sound spectrogram is one of the most fundamental tools of digital speech processing. The sound spectrogram of a speech file is an image map of the sequence of short-time log (or linear) spectrums, where each spectrum is obtained from an STFT analysis of a frame of speech, and subsequent spectrums are obtained from STFT analyses of subsequent, highly overlapped in time ...
When working with spectral representations of audio, the mel scale is a common reweighting of the frequency dimension, which results in a lower-dimensional and more perceptually-relevant representation of the audio. tf.contrib.signal.linear_to_mel_weight_matrix produces a matrix you can use to convert a spectrogram to the mel scale.
Your use of functions like im2double (I'm not sure why you would use this anyway, isn't the output of specgram already double?) and blockproc indicate you are treating the spectrogram as an image. It's an image only for convenience of display.
Jan 10, 2015 · Using Timeside for Spectrogram generation. TimeSide is a set of python components enabling low and high level audio analysis, imaging, and transcoding (conversion of one digital code to another) and streaming. Its high-level API is designed to enable complex processing on large datasets of audio and video assets of any format.

Dec 29, 2019 · 2.3 The spectrogram. 2.3.1 Spectrograms of heartbeat audio. Spectral engineering is one of the most common techniques in machine learning for time series data. Spectrograms of audio can be used to identify spoken words phonetically, and to analyse the various calls of animals. A spectrogram can be generated by an optical spectrometer , a bank of band-pass filters , by Fourier transform or by a wavelet transform (in which case it is also known as a scaleogram or scalogram ).
