This is all the code we need for amplitude modulation. Much of the processing can be done by using the Wolfram Language’s arithmetic functions all of them work seamlessly on Audio objects. To make the result sound less dry, we can apply some reverberation using AudioReverb. We can start by deleting silent intervals.įinally, speed up the result using AudioTimeStretch. Let’s try to replicate what often happens at the end of commercials: speed up a normal recording without losing words. With a little effort, it is also possible to apply more refined processing. It is easy to manipulate sample values or perform basic edits, such as trimming.Ī fun special effect consists of increasing the pitch of a recording without changing the speed. WienerFilter can be useful in removing background noise.Ī lot of audio-specific functionality has been developed for editing and processing Audio objects-for example, editing ( AudioTrim, AudioPad, AudioNormalize, AudioResample), to visualization ( AudioPlot, Spectrogram, Periodogram), special effects ( AudioPitchShift, AudioTimeStretch, AudioReverb) and analysis ( AudioLocalMeasurements, AudioMeasurements, AudioIntervals). Use LowpassFilter to make a recording less harsh. As an example, we have complex filters at our disposal with very little effort. The Wolfram Language has a lot of native features for audio processing.

Now that we know what Audio objects are and how to create them, what can we do with them? The AudioGenerator function also supports pure functions, random processes and TimeSeries as input. Various commonly generated audio signals can be easily and efficiently created using the new AudioGenerator function, ranging from basic waveform and noise models to more complex signals. The out-of-core representation of the same file is only a few hundred bytes.Īudio objects can be created using an explicit list of values. The file size of the two-minute Bach piece above is almost 50MB, uncompressed. This allows us to deal with big recordings or large collections of audio files without the need for any special attention. In addition to importing and storing every sample value in memory, an Audio object can reference an external object, which means that all the processing is done by streaming the samples from a local or remote file. The Audio object is represented by a playable user interface and stores the signal as a collection of sample values, along with some properties such as sample rate. That’s why the audio capabilities in the Wolfram Language are special: the ability to deal with audio objects is combined with all the knowledge and computational power of the Wolfram Language!įirst, we needed a brand-new atomic object in the language: the Audio object. There are many programming languages that focus on music and sound, but complex operations (such as sampling a number from a special distribution, or the simulation of random processes) often require a lot of effort. I didn’t need to buy expensive and esoteric gear I just needed to write some (or a lot!) of code. I picked up the guitar in high school, but once I began learning to program, the idea of being able to create and process any sound using a computer was liberating.
I started learning to play guitar, and later at the University of Trieste, I learned about acoustics and signal processing.
In high school, I started wondering how it is that music seems to be so universally pleasing, and how it differs from other kinds of sounds and noises.
