Flash uses Mp3 as its audio. The resolution is 320 x 240 (which they blow up); &nbsp;there's also HD resolution -- just read YouTube's definition of this. or Google YouTube High Definition. YouTube also often uses mono sound, so if you want to upload stereo you should upload in H.264 or MPEG-2. You might also try wmv. Don't convert to flash to upload to YouTube, this is a wast of time and usually not successfull as YouTube completely recodes your video.<br />

Digital audio is technology that can be used to record, store, generate, manipulate, and reproduce sound using audio signals encoded in digital form. Following significant advances in technology, digital rapidly replaced analog audio technology in most areas. Digital audio systems may include compression, storage, processing and transmission components. It is important to distinguish between the audio coding format, the codec performing the encoding and decoding of the raw audio data, and the container file. Common file formats include .wav, .aiff, .au, .m4a, .mp3, .wma, .ra and .raw.
