..: Broadcast Audio Processing :..

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.

Features:
Declipper:
– Repairs clipped audio
– Removes distortion, restores dynamics
– Also used by police forensics labs

Delossifier:
– Improves the sound of MPEG2/MP3 style lossy compressed files

Dehummer:
– Removes unwanted constant sounds, such as a 50/60 Hz hum from bad cables

Spectrum control:
– Non-compressing spectrum equalization

Compressors:
– Wideband AGC
– Two multiband compressors, 2-9 bands
– Wideband compressor
– Low level boost for classical music

Stereo widening:
– Choice of multiple stereo wideners

Loud & clean!:
– Upto 140% audio level at 100% modulation
– Gives 2-3 dB extra headroom for highs
– Be the loudest and cleanest station on the dial!

Multipath:
– Controls RF bandwidth to avoid reception problems
– Compatible with all receivers
– Stations report upto 30 km bigger reception area

Stereo / rds:
– Built-in stereo and RDS encoder
– RT+ and remote control support

Changes:
– Added generated translations. Let us know if you miss a language or find translation errors.
– Multiband compressor: Changed band linking behavior to respond with a delay. Avoids sudden wideband drops.
– Multiband compressor: Added band linking from 3rd to last to last band to prevent excessive highs.
– Enterprise: Intrasonics watermarking: Added support for ConsumerH8 codewords.
– I/O: Updated PortAudio to latest version.
– I/O rewrite: Sound cards are now opened with as many channels as there are available (not for MME/DirectSound).
– I/O: Sound card errors are now separated per input/output target, and no longer displayed after fixing in the buffer meters.
– I/O: Increased AES67 input network buffer size to prevent dropouts on high CPU usage in high priority threads.
– I/O: Linux: AES67 LiveWire incoming stream detection didn’t work on Linux.
– Some errors now overwrite (replace) older error messages (in Stereo Tool).
– All programs show a very clear error message if $HOME is not set on Linux, so settings cannot be stored.
– Web interface: Added RDS display.
– Bug fix: Since version 10.60, Stereo Tool could end up in a cycle where it kept complaining about audio glitches, typically after rebooting.
– Bug fix: Multiband compressors in matrix mode caused weird hum on 5.1, 7.4.1 audio. Matrix mode is now disabled for > 2 channels.
– Bug fix: STXtreme: Input 2 mode setting (backup etc) sometimes didn’t work until reboot.
– Bug fix: Command line progress display was mangled due to UTF-8 issue.
– Bug fix: Issue in postponed low latency output initialization in plugins.
– Bug fix: Phase Delay and Stereo Reverb could cause loud bursts on settings changes that could trip other things in the chain.
– Bug fix: Streaming output could hang if now playing info was read from a remote drive that became unreachable, causing timeout errors.
– Bug fix: Web interface: Clear error buttons often didn’t work.
– Bug fix: Web interface: Visiting Declipper scopes setting could cause crash in Linux since version 10.50.
– Bug fix: Sometimes a warning was logged on Linux about being unable to set a thread priority or nice level.
– libStereoTool: Added web interface and UECP port binding for safer integration without external access to web server.
– libStereoTool: Added option to override default priority levels (needed to avoid glitches in external AES67 receivers).
– libStereoTool: Added stereoTool_SetRdsBitCallback function to externally feed RDS data.
– MicroMPX decoder: Bug fix: GPS: On some devices, obtaining loopback lock could cause 1PPS pulses to be no longer detected, disabling GPS lock.
– MicroMPX decoder: Bug fix: HF tilt value below 0.220 caused weird results (Nyquist).
– MicroMPX encoder: Increased USB delay range; Leo Bodnar GPSDO seems to need around 500 ms.
– MicroMPX encoder: Improved validity check for incoming RDS signal.
– MicroMPX encoder: Added Multicast TTL setting to override default (1).
– MicroMPX: Bug fix: Changing sound card in encoder didn’t work until restarting since version 4.3.0.
– MicroMPX: Bug fix: ^C on Linux didn’t close encoder or decoder.
– Updated presets.
