Soundwave was made available for Harmattan back in January, but as of today you are able to download the SoundHound powered and Midomi libaries using music recognition app for your Symbian Belle phone. 
Just like the Harmattan version, Soundwave on Symbian costs 5€. Something that will probably scare some of the people interested.

What is it?

Soundwave is an application for music recognition. It uses Midomi servers to identify and search for patterns. Upon success, you will be presented with various data about track, album and artist that you are currently listening to.

How does it work?

Just click on the icon, watch a nice rotating animated pie and standby. Once powerful servers have found a match, you will be presented with the result. If no match is found, you will be told too.

You need more info?

Further information and interaction can be obtained over Soundwave on Facebook or contacting author on Twitter or simply sending an email

With Symbian you don’t really have much of a choice if you are owner of some the newer Symbian phones and Bojan Komljenovic, who is the developer of the app is very active so you can expect updates in the future. We actually touched on the possible updates on the original Harmattan post.
