Processor Music

[Hayley Sweigard]

Iam just planning to buy one multiFX processor. I like Zoom G5n. It just sounds great.I have Zoom's G1Xon. It is pretty good. Not that much amazing. But problem is, the volume level is not consistent throughout the patches. Volume fluctuates whenever i go from one patch to another. I was playing some rhythm stuff using clean tones in a church. When the time for a solo came i just changed the patch to some distortion. Suddenly the volume raised to its peak level when i played my first note. Everybody including the band members got shocked. That was the issue. Now also this pedal has the same issue. Now am using Vox Stomplab 2g. I don't have any volume issues with Vox. I just want to buy Zoom G5n. I've seen some reviews on YouTube. It just sounds amazing. But am afraid of the volume fluctuation issue. Is there anybody using this pedal? Can someone guide me.. Also I want to know about its built quality. Is it made of plastic or metal? Is it hard enough to carry on the road ??Thank you so much...Wesli

I can't tell definitively from the pictures whether it's metal or plastic because of the matte black color, but it looks like the housing might be metal and some of the foot switches are plastic. In either case, Zoom has never really been known for great build quality. That said, if you take care of it and keep it protected while in transit, it should be fine.

Hard enough to carry on the road? That issue is easily solved by getting a decent briefcase, fitting it with some foam, and always using it to transport. There's room in a case for the pedalboard, leads and mains adaptor, and it looks professional too.

What I can say is that it is very versatile and the amp simulations are nice sounding. The patch volume issue can be easily addressed setting the master volume of each patch. The casing is mostly plastic, but looks solid enough.

This thread aims to explore the use of Python and libraries for creative audio processing and sound manipulation both in real-time and for offline work with audio files, but also for MIDI sequencing, audio synthesis etc.

Feel free to share your experiences with the libraries listed above, provide or ask for advice, recommend other Python libraries useful for creative audio processing, or share code snippets, books, articles, etc.

Pyo is a Python module written in C to help digital signal processing script creation. It provides a complete set of classes to build audio softwares, compose algorithmic musics or simply explore audio processing

Hacker Noon - Audio Handling Basics: Process Audio Files In Command-Line or Python

This article provides a primer on handling audio data using command-line tools and Python, offering a cursory exploration into sound handling in Python. It elucidates the two fundamental attributes of sound: amplitude and frequency, and discusses the importance of sampling frequency in the audio processing domain. Practical examples including normalization and trimming/segmentation, etc

The Clever Programmer - Audio processing with python / Pydub

A beginner-friendly guide using the PyDub library. It covers loading files, playing, basic processing, layering, applying filters, and synthesizing tunes with Python.

Below is a list of readings that I have found enjoyable and informative on the journey of learning Python or enhancing existing skills. While they are not specifically focused on sound processing, acquiring a good grasp of Python fundamentals through these resources can provide a solid foundation for those interested in exploring audio manipulation techniques.

Almost ten years ago I took a Coursera course, Audio Signal Processing for Music Applications, taught by Xavier Serra at Universitat Pompeu Fabra, and the bulk of the signal processing was done with numpy. It looks like that course is still going; I thought it was pretty great.

AMY is also the basis for the Alles distributed mesh synth, and the sound engine in the Tulip Creative Computer, which are other projects from the same talented developers and worth checking out if you enjoy using Python for creative pursuits:

If you have notation software, you have probably found that the fonts designed for them are practically useless in a word processor. Fortunately, there are some fonts that are designed with teachers in mind. I will show you two helpful tools that I use to create worksheets for my students.

The motivation for audio signal processing began at the beginning of the 20th century with inventions like the telephone, phonograph, and radio that allowed for the transmission and storage of audio signals. Audio processing was necessary for early radio broadcasting, as there were many problems with studio-to-transmitter links.[1] The theory of signal processing and its application to audio was largely developed at Bell Labs in the mid 20th century. Claude Shannon and Harry Nyquist's early work on communication theory, sampling theory and pulse-code modulation (PCM) laid the foundations for the field. In 1957, Max Mathews became the first person to synthesize audio from a computer, giving birth to computer music.

Major developments in digital audio coding and audio data compression include differential pulse-code modulation (DPCM) by C. Chapin Cutler at Bell Labs in 1950,[2] linear predictive coding (LPC) by Fumitada Itakura (Nagoya University) and Shuzo Saito (Nippon Telegraph and Telephone) in 1966,[3] adaptive DPCM (ADPCM) by P. Cummiskey, Nikil S. Jayant and James L. Flanagan at Bell Labs in 1973,[4][5] discrete cosine transform (DCT) coding by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974,[6] and modified discrete cosine transform (MDCT) coding by J. P. Princen, A. W. Johnson and A. B. Bradley at the University of Surrey in 1987.[7] LPC is the basis for perceptual coding and is widely used in speech coding,[8] while MDCT coding is widely used in modern audio coding formats such as MP3[9] and Advanced Audio Coding (AAC).[10]

An analog audio signal is a continuous signal represented by an electrical voltage or current that is analogous to the sound waves in the air. Analog signal processing then involves physically altering the continuous signal by changing the voltage or current or charge via electrical circuits.

Historically, before the advent of widespread digital technology, analog was the only method by which to manipulate a signal. Since that time, as computers and software have become more capable and affordable, digital signal processing has become the method of choice. However, in music applications, analog technology is often still desirable as it often produces nonlinear responses that are difficult to replicate with digital filters.

A digital representation expresses the audio waveform as a sequence of symbols, usually binary numbers. This permits signal processing using digital circuits such as digital signal processors, microprocessors and general-purpose computers. Most modern audio systems use a digital approach as the techniques of digital signal processing are much more powerful and efficient than analog domain signal processing.[11]

Processing methods and application areas include storage, data compression, music information retrieval, speech processing, localization, acoustic detection, transmission, noise cancellation, acoustic fingerprinting, sound recognition, synthesis, and enhancement (e.g. equalization, filtering, level compression, echo and reverb removal or addition, etc.).

Audio signal processing is used when broadcasting audio signals in order to enhance their fidelity or optimize for bandwidth or latency. In this domain, the most important audio processing takes place just before the transmitter. The audio processor here must prevent or minimize overmodulation, compensate for non-linear transmitters (a potential issue with medium wave and shortwave broadcasting), and adjust overall loudness to the desired level.
