Cybercorder 2000 was a versatile audio recording software that allowed users to capture audio from various sources, including radios and internet streams. It functioned similarly to a VCR, enabling users to schedule recordings and save them in WAV or MP3 formats on their PC. Although the software is no longer sold or supported, it provided a range of features that made audio recording easy and efficient. Users could listen to audio being captured in real-time and utilize a built-in sound editor for editing recordings. As Cybercorder 2000 has been retired, users are encouraged to consider Total Recorder Professional Edition as a suitable replacement. Total Recorder offers enhanced features such as scheduled recordings, background recording, and the ability to convert and edit sound files. With its user-friendly interface and robust functionality, Total Recorder remains a popular choice for those looking to record audio from various sources, making it a valuable tool for amateur radio enthusiasts and audio recording professionals alike.
