You can use configureMIDI to enable tuning the object using a MIDI device. You can also use audiopluginexample.BassEnhancer in MATLAB just as you would use any other MATLAB object. You can also open a timescope and a spectrumAnalyzer to view and compare the input and output signals in the time and frequency domains, respectively. You can tune the plugin parameters as the test bench is executing. The test bench provides a graphical user interface to help you test your audio plugin in MATLAB. You can open a test bench for audiopluginexample.BassEnhancer using Audio Test Bench. You can incorporate the object into a MATLAB simulation, or use it to generate an audio plugin using generateAudioPlugin. The plugin parameters are the upper cutoff frequency of the bandpass filter, and the gain applied at the output of the bandpass filter (G in the diagram above). Bass Enhancer Audio pluginĪudiopluginexample.BassEnhancer is an audio plugin object that implements the psychoacoustic bass enhancement algorithm. The left and right channels are concatenated into a single matrix and output.Īlthough the resulting output stereo signal does not contain low-frequency elements, the input's bass pitch is preserved thanks to the generated harmonics. y G is added to the left and right highpass channels.Ĩ. y B P, the bandpass filtered signal, passes through tunable gain, G.ħ. The filter's upper cutoff frequency may be adjusted to fine-tune output sound quality.Ħ. y is passed through a bandpass filter with lower cutoff frequency set to the speaker's cutoff frequency. That’s all there is to tuning a bass using harmonics.5. Tune the G-string until the two harmonics match. Pluck the 5th fret harmonic on the D-string. Lastly, on the G-string pluck the 7th fret harmonic. Tune the D-string so these harmonics match. On the A-string play the 5th fret harmonic. On the D-string play the 7th fret harmonic. Points to touch for tuning harmonics on the E- and A-strings. Tune the A-string so the two harmonics match. Be sure you get them ringing at the same time don’t accidentally mute one. On the E-string, play the 5th fret harmonic. On the A-string play the 7th fret harmonic. To tune you will use the harmonics on the 5th and 7th frets. The advantage of using harmonics is you don't have to hold anything down. You can match a harmonic on one string to a harmonic on the other.

Much like was discussed in the lesson on how to tune a bass with fretted notes, you can tune a bass relative to itself using harmonics.

That is probably the most famous song full of bass harmonics. To hear the possibilities of harmonics, listen to Jaco Pastorius - Portrait of Tracy. It may take some practice to get clear, consistent harmonics. It also helps to lift your finger off the string immediately after plucking the harmonic. If you can’t hear the harmonics ring out very well, try using just your bridge pickup. The loudest ones are over frets 5, 7, 9, and 12. To get a harmonic just touch the string, don't press. Pluck the string and you should hear a chime-like sound. Again, don’t press down the string like normal, just touch it gently. You must touch the string directly over the fret. The loudest harmonic occurs at the 12th fret. They are obtained by lightly touching ( not pressing down) the string at certain points on the string. However, there are other “hidden” notes on your bass. Most often notes on the bass are played by pressing the string against a fret.
In case you missed it, you should first read the main bass tuning lesson and the tuning a bass with fretted notes lesson.
