Into Uzbek by Sherali Niyazova, and into Bosnian by Amina Dugalic.The Vocoder is a special machine because it acts more like an effect than a stand-alone synth. Russian by Kirill Sukhorukov, into Norwegian by Lars Olden, You can find translations of this page into You may also be interested to compare this implementation with the C language Zerius Vocoder - you will find that they operate similarly, and indeed, the test files above (carrier22 and modulator22) are taken from the Zerius website. You should be able to run the program and get the same output as "vocodedsound.wav." By using different carrier and modulator sounds, there are a variety of effects that you can create. (You may need to right click to download these files.) After downloading, make sure that they (along with the chanvocoder.m function itself) are placed in the Matlab path. So that you can check to see that everything is working, here are the above carrier and modulator files, along with the output you should hear from the above script. This reads in the two sound files using the wavread command, checks that the sampling rates match (if not, you won't get what you expect), calls the chanvocoder function, and then writes the output as another sound file that you can listen to in Matlab, or using any audio program capable of playing. If sr1~=sr2, disp('your sampling rates dont match') end wav file called "carrier22.wav" and another called "modulator22.wav." A typical way to call the vocoder is: Typically, you will use chanvocoder.m with sound files in the. The sound will change depending on these values.
You can choose the number of channels (the FFTs are of length 2*chan) and the number of bands (how many frequency bands to break the signal into), as well as the amount of overlap between successive FFT frames. These must both have the same number of tracks, i.e., they must either both be mono or both be stereo.
The modulator is typically a voice (speak clearly and slowly) and the carrier is typically a harmonically rich sound source (such as an organ, synthesizer, or colored noise).
