Unfortunately these coefficients do not seem very accurate. ITU-R BS.1770: There are coefficients given in this recommendation for the calculation of inter-sample peaks. This reduces true peak overshoots for proper band-limited audio to 0.2 dB and for pathological signals to 0.5 dB. When ISP is turned on, four additional samples are calculated between every two samples present. from 44.1 to 48 kHz or vice versa, and the use of audio compression such as MP3 or AAC.įor more information see the "Tutorials" section. This can become a problem not only with poor D/A converters, but also with subsequent sample rate conversions, e.g. These true peak overshoots can be up to 3 dB for proper band-limited audio and even much more for pathological signals. The higher the frequency, the greater the probability that the true peak will be between two digital audio samples. Thanks to Hannes Druener for using his MacBook and testing. The GUI was designed by LimeFlavour based on the idea and colorscheme of Sinkmusic. Only one slider for adjusting the maximum amplification. The Winamp Plugin has a simplified user interface. Built-in stereo overdrive protection avoids distortions in a subsequent stereo downmix. The Winamp Plugin also supports 5.1 surround. See README file in the LADSPA zip package for further informations. The Linux Plugin has no meters since LADSPA doesn´t support a custom GUI. The Audio Unit version was built with Symbiosis from NuEdge Development. The Mac OS X Plugins are "Universal Binaries" with support for Intel Mac. LoudMax is available as VST 2.4 Plugin for Windows and Mac OS X, Audio Unit Plugin for Mac OS X, LADSPA Plugin for Linux x86 and as Winamp Plugin.Ī SSE2-capable CPU is necessary (Pentium 4 / AMD Athlon 64 or newer). Release Time: Automatic - depending on the input signal.True Peak Limiting (Further information for ISP below).ISP: Inter-sample peak detection for true peak limiting.Link: Output slider will be coupled to the threshold slider.Meters for input, output and gain reduction in relation to the desired threshold.One slider for threshold, one for the output level.Output Limiter/Maximizer for web radio stations.Inter Sample Peak detection optimized for transparent sound.Better save your existing LoudMax version or update it at the beginning of a new project. Some plugin hosts do not like it to change the number of controls between saving and recall. The new control "ISP" has been added with v1.23. Winamp Plugin v1.27 32/64bit (zipped dll)Ĭaution when updating LoudMax in running projects: GUI-less VST Plugin v1.27 for Windows PC 32/64bit LADSPA Plugin v1.27 for Linux x86 32/64bit VST Plugin v1.27 for Mac OS X 32/64bit (OS 10.5 or higher)ĪU Plugin v1.27 for Mac OS X 32/64bit (OS 10.5 or higher) It is designed to retain the original character of the music as much as possible even at high compression levels. LoudMax is a Look-Ahead Brickwall Loudness Maximizer Plugin with a clean transparent sound.
