The default player for opening WAV files is Windows Media Player. Their quality, however, does surpass that of M4A and MP3. WAV files are much larger than M4A and MP3 files, making them less practical for consumer use on portable players. WAV is the result of IBM and Windows iterating a Resource Interchange File Format (RIFF).
The metadata associated with the audio has been future proofed also to allow new fields to be defined without impacting existing decoders.Waveform Audio (WAV) is the most-popular digital-audio format for uncompressed audio files. A FLAC file also contains several data integrity checks in the header file. The main benefits of a FLAC file in addition to it being lossless is that it can be used for streaming, and decoding is fast, allowing for real time decoding to take place. Using FLAC to compress an audio file to approximately 50% of its original size. FLAC is a format that is recommended to those backing up a CD collection because the sound quality will remain high, whereas MP3 compression will result in a deterioration compared to the original. It is a lossless compression type meaning that the compression takes place without data being discarded. This is known as auditory masking, this allows the discarding of data with minimal loss of quality.Ī combination of Fraunhofer IIS, AT&T Bell Laboratories, Dolby and Sony Corporationįree Lossless Audio Codec, or FLAC for short, is an audio compression technique. The human hearing system cannot hear quiet sounds in the presence of loud sounds of a similar frequency for example, a voice conversation cannot be heard while an aeroplane flies low overhead. The current variant is specified in ISO/IEC standard 14496-3. It is also part of the MPEG-4 standard, it is most widely used to create small digital audio files. It too compresses digital audio files but to a bigger degree. Apple are the biggest users of this format and if you have an iPod or iPhone then you will have come across this format as it is iTunes default audio format.ĪAC is similar in concept to MP3 but goes further. It is at least one tenth the size of CD digital data. AAC is about half the size of MP3 but with better quality. It essentially cuts out, or compresses, information that the human ear cannot pick up thereby making digital files smaller and more easily managed and therefore quicker to download.
