Get better quality with AAC

AAC is the emerging future audio standard that might replace existing ones, such as MP3. It is already supported by popular devices such as Apple iPod, Sony PSP, Sony PS3, Nintendo Wii, various cell phones etc. Some technical snap-shots:

  • AAC and HE-AAC offer a significantly better audio quality while using the same bit rate as other audio codecs, especially for bit rates below 192 kbps.
  • AAC may only need a fraction of the bandwidth than MP3 for your field of application (e.g. broadcasting concerts), thus resulting file sizes will be smaller too.
  • AAC offers a significantly higher coding as well as compression efficiency and allows you a higher flexibility in usage than MP3.

Most importantly, saving bandwidth and having smaller file sizes means saving money – especially if your business relies on continuous video & audio streaming over scarce resources. Providing better audio quality to your audience and encoding efficiency only add to the advantages of the AAC encoding standard. 

AAC was developed to be the successor of MP3. For more technical details on AAC you may refer to comprehensive public documents at Wikipedia.

Adobe Flash Media Live Encoder 3.0 (FMLE) already includes the MainConcept H.264 Encoder technology to create professional video streams. Now using the AAC Encoder Plug-In, it additionally supports AAC (MPEG-4 AAC & HE Audio), enabling you to directly create and stream Flash compliant F4V or FLV files that include both H.264/AVC video and AAC audio. It is the perfect companion for FMLE, as it enables you to generate Flash compliant streams using these encoders on-the-fly. And your files are always compliant with the latest Flash Player version.
