Midomi

Midomi is a popular service that, like its competitor Shazam, is used to identify a song via your iPhone microphone.What sets this app apart is its ability to not only tell you what song is playing, but also the song you sing or hum into it..

Why download this instead of Shazam? It is the same app, right? Wrong. Using what Midomi calls "grabbing," you can choose whether to sing/hum, say, type, or grab the actual song. When you choose to sing/hum the song, you dictate how long the clip will be recording. The same case goes with the grabbing of the music off of a sound source. The typing a song function into a search box is awesome as well for when you have a lyric of a song, but you just can't put your finger on what it is.

The accuracy of Midomi is note-worthy as well. Their song database is then searched for similarities (which also available on their website). The longer you record a song, or the larger amount of text that you input, the more accurate the app is with selecting the song. Background noise can have an effect on the accuracy (people speaking, other music, etc.) but more often then not, it identifies the song correctly. To test, at a party I had a group of (fairly tone deaf) family and friends sing 3 different songs. I recorded each at 20 seconds, and Midomi had picked flawlessly identified the song each time. After the song that is identified, it presents you with the options of buying the song from iTunes, searching on Youtube, bookmarking the song for future reference, and accessing other song info.
