Thimeo Stereo Tool 10.41 / 10.30 / 10.21 / 10.20 / 10.11 / 10.10

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.

If you don’t use Stereo Tool for FM processing, Basic suffices.

FM Standard offers “standard” FM processing, stereo and RDS encoding. The processing in this license is comparable to what many high end (00+) hardware boxes offer. In most markets, this license will make you one of the louder stations on the dial.

FM Professional adds our special Composite Clipper to the processing. This is the same clipper that’s in the Omnia.9sg and the Omnia.9 and Omnia.7 are being upgraded to it. The Composite Clipper takes the stereo pilot, stereo encoding and RDS into account when generating the composite MPX signal, which increases the headroom for audio by a lot. You can typically generate a signal that’s 2-3 dB louder without sounding more clipped, which results in a much more dynamic and much higher fidelity signal. Beside that it unlocks our “Asymmetric L-R” mode, which adds another 1 dB or so. Beside these advantages to the audio signal, the clipper can also analyse the RF spectrum after the exciter, and optimize the signal to reduce reception issues in fringe areas and in multipath areas.

If you can use Stereo Tool to generate the composite MPX signal, we highly recommend the FM Professional version, which sounds much better and improves your reception. To be clear, with FM Standard you’re not doing worse than most high end hardware boxes, but FM Professional really takes it to another level – assuming proper hardware you’ll be the loudest and cleanest station on the dial.

Declipper

Due to the so-called loudness war, where everyone wants their track to sound louder than any other track, nearly all music from the last 20 years or so has been clipped during mastering. This causes several issues:

It sounds distorted
It lacks dynamics
Low bitrate codecs are using a lot of their bits to encode the distortion, leading to much more lossy compression (MP3, AAC, …) artifacts.

To make things worse, audio processing tends to boost softer sounds, in this case, the distortion, which worsens these problems. The Declipper repairs the audio before it enters the processor.

Our declipper is also used by police forensics labs. The following video shows what it does to clipped audio:

Delossifier

The Delossifier improves the sound of lossy compressed audio. It’s targeted at repairing low bitrate MP3 and MPEG2 files. Use this if your playlist contains low bitrate tracks. (But please, do everyone a favor and replace them…. With clipped audio that’s usually not possible, but low bitrate is a different story.

Advanced Dynamics

Advanced Dynamics was added in Stereo Tool version 8.50. It consists of 2 parts:

Auto EQ
Dynamic ratios

Auto EQ is the most spectacular part. It adjusts the sound before the AGC without compressing it. This makes it possible to have a much more consistent output without sounding processed. Since it doesn’t compress the audio, it doesn’t add density and doesn’t cause pumping or breating. Auto EQ can achieve the same spectral consistency that multiband compression can, without those side effects. It does not affect audio levels, only the spectrum.

Dynamic Ratios makes it possible to have a different ratio in the compressors depending on how much they are pushing the level down. When it gets deeper, it gets steeper. So a very loud sound will be compressed more.

This video shows the Auto EQ in action:

v10.41
(4.2.6)
Added Multiband band 2 band linking slider to speech detection.
Bass intermodulation distortion protection is now an Advanced feature because it hardly affects bass anymore.
GUI: Native GUI now has a pulldown with list of errors.
GUI: MPX spectrum meter in native GUI looked bad when using skin with light background.
Web interface: Lots of improvements, among others in the graphs in parametric eq and multiband bands displays.
Web interface: Sliders were not released after taking finger off of screen.
Web interface: Titles not centered if the window is narrow.
Web interface: ID’s are now visible in web interface code when using browser analysis tools.
Web interface: On very small screens, could stop working if widgets were outside of the visible area after loading a page.
Bug fix: When FM or AM processing is on without pre-emphasis, HD output was disabled even when selecting separate processing for streaming.
Bug fix: Fixed “Event license” MicroMPX flag (broke in 10.40).
Bug fix: Entering license key with space at the end caused issues after restarting.
Bug fix: VST behavior hopefully fixed, VST3 on Mac now really available.
Bug fix: Presets loading from native GUI could make multiband bands flip when web interface was open on multiband page.
Bug fix: libStereoTool crashed when opening the GUI inside a parent window. Broke in 10.40.
Bug fix: ITU meter showed MPX output, even if HD output was enabled. (It still shows MPX levels if only MPX output is used.)
Bug fix: GUI: Duplicate toggle button on resource page fixed.
Bug fix: GUI: Fixed Adaptive Compressor license displays.
Bug fix: GUI: Solved redraw problem that sometimes caused text to turn black.
Bug fix: GUI: ST-Enterprise: Fullscreen only worked on instance 1.
Bug fix: GUI: Window position after restart could be outside of the screen, making it impossible to move it.
Bug fix: GUI: Bypass mode didn’t make PDcWave displays disabled.
Bug fix: Web interface: Indentation in top bar menu’s was missing since 10.40.
Bug fix: ST-Enterprise: Web interface: Instance links didn’t work when running ST-Enterprise as a Windows service.
PiMP: Bug fix: AGC stereo settings were shown, but PiMP does not support stereo.
STudio: Bug fix: Crashed when started without a settings file.
Raspberry Pi image: Added support for IQaudIO sound cards.
libStereoTool: User logins enabled.
ST-Enterprise: GUI: Disabled error/warning popups of all instances in the Overview screen (caused problems).
Raspberry Pi image: New Raspbian version requires explicitly calling jackd with 2 input and 2 output channels.
MicroMPX: Windows: Network reliability: QoS DSCP setting CS7 changed to CS5, when running without Admin rights (using EF in Admin mode).
MicroMPX: Linux: Network reliability: QoS DSCP changed from 0xE0 to 0xB8 (Expedited Forwarding).
Updated presets.
