M4P and WMA File Formats

M4P and WMA are two popular audio formats.M4P is the Protected AAC File. AAC is the audio layer from the follow-on format to MP3. The .M4P extension is AAC purchased from Apple's Music Store (iTune) and is protected by a Digital Rights Management scheme.

iTunes: Owned by Apple, the iTunes store set the pattern for a la carte music shopping and still reigns king over the customer base. iTunes has sold more than 5 billion songs to date, and it offers excellent integration with the world's best-selling MP3 player, the iPod. It's catalog contains more than 8 million songs as well as a variety of podcasts, TV shows, and movies. The one major bummer is that most of the tracks sold in iTunes can only be played on the iPod or iPhone and not any other MP3 player. You must download the iTunes software in order to access the store, but it works on both Windows and Mac operating systems.

Windows Media Audio (WMA) is the most common codec of the four WMA codecs. Colloquial usage of the term WMA, especially in marketing materials and device specifications, usually refers to this codec only. The first version of the codec released in 1999 is regarded as WMA

WMA can sample audio signals at up to 48000 times per second (48 kHz) with up to two discrete channels (stereo). WMA 9 introduced variable bit rate (VBR) and average bit rate (ABR) coding techniques into the MS encoder although both were technically supported by the original format. WMA 9.1 also added support for low-delay audio,[19] which reduces latency for encoding and decoding.

eMusic: This indie representer is quite a ways behind iTunes in catalog numbers and sales, but it controls the second largest market share (10 to 15 percent, according to label feedback). eMusic has sold more than 200 million tracks in the past four years and is currently averaging five to six million song downloads per month from its catalog of over 3.5 million tracks. The company made a name for itself with an all-you-can-download service but now offers limited subscriptions, starting at $11.99 per month for 30 unrestricted MP3s. Thanks to this "track pack" pricing and the fact that the company doesn't currently sell big label songs, eMusic offers an incredible value: it is the cheapest of the bunch by far (27 cents per track with the Premium plan). It also has a large number of music reviews by editors and users alike.
