The ML-compatible A52Codec.component will have a timestamp of Jul 27, 2012. If you have installed Perian, it'll put its own version of A52Codec.component with the timestamp Jul 23, 2011 (it's based on these timestamps that you can easily know which version is currently installed). Apr 10, 2007 -from engadget thanks guys for this awesome how to The two biggest Apple TV limitations are the lack of codec support (like XviD, DivX, etc.) and not even having the ability to do basic surround sound like Dolby Digital 5.1. These issues were resolved almost immediately after the Apple TV was released, although the hacks.
A52 Codec Editor's Review
A52 is a free codec that allows you to play media files that use the AC3 encoding.As a rule, you can find the AC3 audio encoding within the DVD movies or native multi-channel music that can use this type of encoding. This codec is also required by Perian plug-in, when it's decoding a movie that has in its container an AC3 audio stream.
The codec is implemented as code-audio component. This means you can use it both in QuickTime and Core Audio components.
The support for QuickTime is well implemented. It includes an importer in order to play the *.ac3 files directly from this player.
Within the DMG install image, you find a component that can enable/disable some of this codec features. The filters that you can control with this application are: Dynamic Range Compression and a downmix filter. The downmix filter generates a stereo output from a native multi-channel source. Pluses: It does a good job, when support for AC3 audio encoding is required.
Drawbacks / flaws:
In conclusion: this is a nice plug-in that helps you a lot if you use AC3 as an audio compressor for your music or if you have movies that uses this codec within their containers.

Windows[edit]
Windows built-in speech recognition[edit]
The Windows Speech Recognition version 8.0 by Microsoft comes built into Windows Vista, Windows 7, Windows 8 and Windows 10.Speech Recognition is available only in English, French, Spanish, German, Japanese, Simplified Chinese, and Traditional Chinese and only in the corresponding version of Windows; meaning you cannot use the speech recognition engine in one language if you use a version of Windows in another language. Windows 7 Ultimate and Windows 8 Pro allow you to change the system language, and therefore change which speech engine is available. Windows Speech Recognition evolved into Cortana (software), a personal assistant included in Windows 10.
Add-ons for Windows 7 speech recognition[edit]
- Voice Finger – software for Windows Vista and Windows 7 that improves the Windows speech recognition system by adding several extensions to accelerate and improve the mouse and keyboard control.
Windows 7, 8, 10 third-party speech recognition[edit]
- Braina – Dictate into third party software and websites[3], fill web forms and execute vocal commands.[4]
- Dragon NaturallySpeaking from Nuance Communications – Successor to the older DragonDictate product. Focus on dictation. 64-bit Windows support since version 10.1.
- SpeechMagic – Nuance Communications acquired Philips owned. Medical industry focus according to Frost & Sullivan. Standalone or embedded.[5]
- Tazti – Create speech command profiles to play PC games and control applications – programs. Create speech commands to open files, folders, webpages, applications. Windows 7, Windows 8 and Windows 8.1 versions.[6]
Windows XP or 2000 only[edit]
- Microsoft Speech API – Speech recognition functionality included as part of Microsoft Office and on Tablet PCs running Microsoft Windows XP Tablet PC Edition. It can also be downloaded as part of the Speech SDK 5.1 for Windows applications, but since that is aimed at developers building speech applications, the pure SDK form lacks any user interface, and thus is unsuitable for end users.
Built-in software[edit]
- Microsoft Kinect includes built-in software which allows speech recognition of commands.
- Older generations of Nokia phones like Nokia N Series (before using Windows 7 mobile technology) used speech-recognition with family names from contact list and a few commands.
- Siri, originally implemented in the iPhone 4S, Apple's personal assistant for iOS, which uses technology from Nuance Communications.
- Cortana (software), Microsoft's personal assistant built into Windows Phone and Windows 10.
