Vox Recorder is a specialized Windows utility designed for amateur radio operators, and radio listeners particularly those who use radio scanners. This software allows users to record audio from various sources, but it only activates when an audio signal is detected. This feature is particularly useful for avoiding the capture of silence or background noise, which can be common in radio scanning. By focusing on the audio signals, users can create cleaner recordings that are more relevant to their interests. The utility is user-friendly and tailored for hobbyists who want to document their radio listening experiences without the hassle of editing out silence later. Vox Recorder is an excellent tool for anyone involved in amateur radio, as it streamlines the recording process and enhances the overall experience of monitoring radio frequencies. Whether for personal use or for sharing with fellow enthusiasts, Vox Recorder helps ensure that every important transmission is captured effectively.

Capturing intermittent radio transmissions efficiently requires a robust audio recording solution that can intelligently manage disk space. Scanrec, a freeware Windows application, addresses this by providing a **Voice Operated Exchange (VOX)** control feature, enabling the recorder to activate only when audio signals exceed a user-defined threshold. This functionality is particularly effective for **FM communications** due to their strong squelch characteristics, minimizing recordings of static or noise. The software supports recording radio communications, air traffic control, and infrequently active channels, preserving disk space by pausing when no sound is detected. It incorporates an anti-clipping feature to ensure the beginning of audio events is not lost, a common issue with mechanical VOX systems. Output files are saved in WAV format, compatible with standard Windows Media Player. Scanrec operates on older Windows systems including Win95, Win98, NT, W2000, and XP, requiring minimal resources like a 486 PC, 4 MB RAM, and a sound card with line or microphone input. While optimized for FM, its VOX gate can be challenging to set for HF ham bands and World Band radio due to their poorer signal-to-noise ratios.

Audiocorder is a VOX program which allows your Macintosh to act as an audio recorder

Vox Recorder is a Windows utility wich allows recording sound from an audio source only when an audio signal is present; its main purpose is to avoid the recording of the silence eventually present at the input.

The page provides a utility to record QSOs for amateur radio operators, allowing them to send the recorded signal back to the other station. It addresses challenges with VOX capability in radios and offers solutions for different radio models.

Vox recorder is activated by voice and sounds exceeding a threshold. It saves for every record a .caf file that you can play, delete or send by email. Useful for surveillance records, hamradio scanners, and many many other applications. You'll be surprised to hear what happens in an all night using Vox recorder.
