AC3 Normalizer 2.0
This application addresses some of the volume issues with transcoded AC3 files more>> This application addresses some of the volume issues with transcoded AC3 files
This application addresses some of the volume issues with transcoded AC3 files. It is based on a Soopa toolkit, just in a GUI format. Soopa created some batch files, which use AviSynth, Aften and WAVI.
It is very easy to use. You can either process a group of AC3 files in a specified folder, or drag and drop AC3 files into the application folder for processing. You can select your own bitrate and level of dynamic range compression.
System requirements:
- AviSynth 2.57 or higher
Enhancements:
- bug fixes

SE Normalizer 1.0
A VST plugin that was designed to denormal eleminator plugin effect. more>>
A VST plugin that was designed to denormal eleminator plugin effect. Denormalisation is an issue with some audio hosts that dont switch off the plugins audio task when the song is stopped or a track contains silence (or with instruments: no key is pressed while a sound decays).
The problem happens when the CPU (precisely: the floating point unit (FPU) inside of it) detects extremely small numbers and wishes to process them with the same precision as usual. Then it switches into denormal mode which is another way of representing small floating point numbers with the available bit range. Converting between the two states takes a lot of time for the FPU and thus might cause heavy load jumps.
Some algorithm such as delay lines and filters are prone to denormalisation as they work with feedback structures. Here, if an impulse is followed by absolute silence, the resulting signal gets smaller and smaller but in theory, it can never reach zero. In practice, there is an internal threshold of the FPU that switches to denormal mode to carry on processing those small numbers (which might not be of any use for proper operation).
Currently, the Pentium 4 processor seems highly addicted to denormalisation. It turned out that its threshold is actually very much higher than of former Pentium types. Plugins that used to work fine with older CPUs might slow down the entire system when used with a P4. But other FPUs might as well suffer from denormalisation issues.
Most developers are aware of denormalisation although the methods to avoid it are many. Some algorithms ask for the current FPU status from time to time, reacting to it by changing small values to zero.
SE Normalizer plugin was designed to denormal eleminator plugin effect.
Other developers prefer adding an an extra signal to the audio which is carried along the entire process of the plugin, thereby forcing it to remain above the internal threshold. Should the input become silent, the additional noise will still keep the whole thing from denormalizing. All the digitalfishphones plugins actually work this way, and so does the normalizer.

MIDI Normalizer 1.0.0.5
MidiDesigns MIDI Normalizer is a batch editor for midi files more>>
MidiDesigns MIDI Normalizer application is a batch editor for midi files.
If you have hundreds of midi files and find it annoying that, when playing the files, the volume level is very different for every file, MIDI Normalizer automates the process of leveling the volume, just like that normalizer you already have for normalizing your MP3 collection.
Besides normalizing, MIDI Normalizer can carry out the following tasks:
- Compressing - I found out that it isnt always enough to just normalize the file. In some cases, a midifile has velocity values between 60 and 100, easy to normalize to values between 80 and 120. But if the velocity values are ranging from lets say 20 to 127, then theres no room left for normalizing, and all low values will stay too low. The solution: compressing the velocity values. So theres a build in compressor, that can first compress all velocity values before normalizing is applied.
- Automix - If you spend months of work to remix your files for your keyboard X, but now you bought a brand new "super deluxe" keyboard Y, only to find out that all guitar sounds are too low, and all bass sounds are too loud, then you should take a closer look at the automix function. It allows you to add or subtract a predefined volume value per instrument. This function will also make you happy if youre playing in a combo with f.i. a bass player, guitar player and a singer, and therefore all bass and guitar tracks should be muted from all midifiles.
- ChannelMute - Speaking about a singer, lots of midifiles do contain a lead vocal track on MIDI channel 4. It would be very useful to be able to mute channel 4 to get rid of these vocal tracks. That is possible with the "ChannelMute" function.
- Extracting lyrics - If the midifile contains songlyrics, you can extract these lyrics and save them to a text file.
- Creating tracksheets - The software collects information about every midifile while scanning the files. You can optionally save this information to a textfile.
- Creating playlists - When you have added midifiles from different folders, you can easely save the created filelist to a playlist. Very useful when you want to play a list created by yourself. Even more useful when you have processed your files, and afterwards would like to redo the processing because the process settings were not optimal.
- Built in MIDI player - Theres a basic midiplayer included to play the selected files from the filelist.

AC3Filter is a DirectShow filter for AC3 decoding used to play AVI with AC3 audio tracks and MPEG2. It is distributed absolutely for free (FREEWARE, OpenSource).
AC3Filter is a high quality free audio decoder and processor filter. It allows media players to playback movies with AC3 and DTS audio tracks. Also it can process any audio track, much of processing options allows to adjust the sound in almost any way. It is possible to upmix any audio source to 6 channels. Filter can do multi-channel and digital (SPDIF) output. It can encode any audio source to AC3 on-the-fly and send it over SPDIF to the receiver.
With AC3Filter you can:Playback:
Watch movies with AC3 and DTS audio tracks
Listen multi-channel (AC3/DTS) AudioCD
Playback WAV files with AC3/DTS content, ripped from multi-channel AudioCD without any conversion of these files.
Playback raw .AC3 and DTS files (with help of AC3File filter)
Process:
Up-mix any audio track (even plain stereo) up to 6 channels
Down-mix any audio track to any number of channels (to match your speaker configuration)
If you have an external Dolby ProLogic decoder, you may use ProLogic down-mix to help DPL decoder to extract surround information
Watch movies under poor hearing conditions (noisy environment, weak speakers, ...)
Decrease dynamic range to watch movies at night
Apply time shift to the audio track to synchronize audio with video.
Adjust gain of every input/output channel independently to compensate loudness differences
Adjust time delays for every channel to compensate different distances to loudspeakers.
SPDIF output:
Passthrough AC3 and DTS over SPDIF without any change to external decoder
Encode any audio to AC3 and transmit it over SPDIF
USB sound cards supported<<less
