Microphone Audio Compressor in SSB Radio Single-sideband (SSB) radio, a dominant mode in amateur (ham) radio and other communication applications, transmits voice signals with improved spectral efficiency compared to older AM (amplitude modulation) methods. However, SSB has limitations in terms of audio quality and intelligibility, particularly in challenging propagation conditions. This is where …
Microphone compressor using two transistors Microphone compression is a useful tool that can help you to achieve a more consistent and polished sound. By reducing the gain of the loudest parts of your signal, compression can help to even out your volume levels and make your voice sound more upfront in the mix. It can …
Dynamic speech compressor or simply audio compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, therefore reducing or compressing an audio signal’s dynamic range. Compression is commonly used in sound recording and reproduction, broadcasting, hearing aid, live sound reinforcement, and in some instrument amplifiers. There are …
SSM2167 Microphone Preamplifier with compression for ubitx HF Transceiver This DIY project idea based on the small board module “SSM2167 Microphone Preamplifier Board Preamp Compression Module DC 3V-5V” widely available on eBay and Aliexpress. Mic gain is barely adequate on the µBITx transceiver since there is no Mic Gain control. It would also be helpful …
