ESSB
hi-fi radio signal quality
In the course of the initial struggle with propaganda on the air, I noticed a characteristic feature in the construction of the signal of my station. The higher the quality of your signal, the less power your station needs to read your signal even through interference and range in the radio.
In addition to the fact that such a signal sounds very beautiful and formed, it also has the above advantages. Realizing such a vivid manifestation of the processed signal, I began to engage in ESSB processing.
Since I am very familiar with computers at a high level, I decided to turn my attention to software processing. I understand that older radio amateurs will not be able to repeat my experience, since they are not familiar with the computer at the proper level and also do not know English.
From my experiments, even for such elderly radio amateurs, I can offer a couple of DIY microphone circuits to improve the quality of your signal in the radio
In the process of experimenting with processing, I found out that using only a number is stupid and not practical. The heart of your signal is your microphone. The better the quality of your microphone, the higher the result of your signal. After the microphone, you need a tube preamp for your microphone. After the tube MIC2200 comes Virtualizer PRO DSP 2024P, even such a minimal set is enough to get a decent signal. As for the microphone. The microphone needs a condenser, the more expensive the better. I personally use Neumann U87. But I can say that a $100 microphone won’t be bad either.
Neumann U87 best microphone for ESSB

dsp 2024p
One of the best universal effects processor from BEHRINGER. Previously, its price was $550. Now you can buy it used for $100. Great machine for ESSB signal.

Behringer VIRTUALIZER PRO DSP2024P Digital Multi-Effects 24-bit Multi-Effects Processor
The processor offers 71 impressive new processing algorithms, including modulation, amp simulation, distortion, plus various special effects, as well as dynamic, psychoacoustic and frequency processing algorithms, topped off by our acclaimed “VIRTUAL ROOM” adaptive wave reverb algorithms. Each preset has up to seven adjustable parameters, plus bass and treble EQ. Add to this 11 combinations of effects (serial and parallel), true stereo processing in most algorithms and an improved user interface – you have the best VIRTUALIZER PRO.
71 new algorithms:
New VIRTUAL ROOM reverb algorithms, as well as various modulation and special effects previously only available in MODULIZER PRO, such as Ring Modulator, Lo-Fi, Vinylizer and Voice Canceller. Many additional dynamic and psychoacoustic processing algorithms, Distortion, Amp-Simulation, Sampler, Vocoder and many others.
11 effect combinations:
Popular modulation effects such as Chorus, Flanger, Pitch and oder Tremolo combined with reverb and delay algorithms.
Advanced editing options:
Optimal tuning of the DSP2024P effects is provided by the ability to edit up to 7 parameters, as well as an additional low and high EQ in each preset. 100 factory presets equip you with the necessary set of effects and serve as the basis for your own programs, stored in 100 user memories.
All the solutions in my article were obtained over 10 years of trial and error in signal processing on the air. Hearing terrible signals on the radio, I want to help radio amateurs create and build a decent quality of their signal.

A simple program for essb audio mulch!
There are a lot of programs for writing Music. But radio amateurs who are fond of ESSB signal processing use mainly two programs. One is Audio Mulch, the other is Waves MultiRack. I use FL STUDIO for my voice processing. But it is very difficult to use. In my opinion, Audio Mulch is a simple and high-quality solution for most radio amateurs. I got a good and decent quality in processing on the Audio Mulch program. The video shows in detail how and from what the ESSB signal processing is created. Of course everything is in English. A little later I will make a video tutorial in the Russian language. The VST plugins that are used in this video to shape the signal are partly free, partly paid. You can find them in the public domain on the Internet.

AudioMulch is an interactive, complete music environment that can be perfectly used for live music performance, sound design and composition.
AudioMulch is a modular (or as they say “modular”) sound synthesis and processing system that is suitable for both sound synthesis for subsequent work in post-processing, and for live performance .
The essence of the program is to give the user complete freedom of action. There are many, many different sound processing and creation modules in the set.
AudioMulch is a really powerful and creative system that uses a non-linear signal flow process that is great for ESSB. With its versatile control and automation features, you can synthesize, process and sequence your voice.
With more advanced features like sync, quick configuration, modification, music recording and more, you’ll be sure AudioMulch will help you create beautiful processing of your ESSB signal.
