七、适用人群
Stereo tool is a software-based audio processor which offers outstanding audio quality and comes with many unique features. It is used by over 1500 FM stations ranging from small local stations to 50-100 kW stations and nation-wide networks with dozens of transmitters, thousands of streaming stations and many DAB+, HD, AM and TV stations. It can be used for both live and file based processing.
Stereo Tool can make recordings sound equal and consistent in volume and sound color, bring out the details, and increase existing stereo effects. It can repair ‘broken’ stereo images which often occur on cassette tapes, vinyl and cheap CD’s, which normally causes havoc when playing it on a mono system, headphones or a system which includes a stereo widener.
Special support (not free) is included for radio stations: Much louder output levels, FM pre-emphasis, stereo coding and RDS coding for FM stations, and protection of highs against distortion caused by lossy compression for web radio stations. The processing latency can be reduced as low as 12 ms, at the cost of reduced fidelity. At the maximum quality the processing latency is 93 ms.
Winamp plug-in version
Intended for Winamp, SAM Broadcaster, RadioBOSS, MediaMonkey, AIMP and other applications that support Winamp DSP plug-ins.
Stand alone version
Sound card input to sound card output. Intended mainly for FM radio stations which process external (live) feeds.
System Requirements: Windows XP SP3, Vista, 7, 8, 10 and 11
