So I was always a PC/Windows guy. I just liked to tinker with ISA cards and setting IRQs in the Windows 3.1 days.
Jump ahead to the iPhone, or in my case, the iPod touch. And that did change a lot of things for me. My habits changed. I was reading my email on my morning commute. I got Beatmaker the first day (I am the first member on the INTUA forum). Beatmaker is just a great tool to make music so I decided I wanted to help make it even better. www.ibeatmaker.com is providing space for custom bm kits. and people are still uploading new kits every week.
Now BM is great at creating music. But part of my music creation is also equalizing. There is no Equalizer app for iPhone.
Well, now there is:
You can equalize your music by setting gain or cut on up to seven frequency bands.
Upload your music files via wifi (via web browser, no separate software needed!) to Equalizer and download equalized files for further processing or inclusion in your library.
Internal calculations are done in 64 bit floating point, the industry standard in digital sound processing. During conversion to 16 bit (CD quality) you have the option of dithering the sound to reduce artifacts and lower the noise level (noise shaping) both in real time while editing as well as when rendering the music file to disc. A control light warns you from over equalizing your audio. Use the pre-EQ volume slider to prevent clipping.
Best results are achieved if your music files are 44.1kHz sampling rate at 16 bit, the typical .wav format that corresponds to CD quality. Compressed file format support like ma4 and mp3 is planned for future updates.
Unfortunatly there is no direct access to the iTunes library on your device. This is a limitation imposed by Apple and there is currently nothing (short of Jailbreaking) to go around that.
So this little app is great for fine tuning your samples but also your final song. Yet again another step for music production is made available on the iPhone.
I am not done with Equalizer yet. As of right now, I am working on a frequency domain display that is a must for a good equalizer. Then I will add functionality to decode other file formats, right now only 16 bit wav is supported. So I will post back when there is more news. If you want to request any features, feel free to comment.
On a more personal note: I am quite proud of how it all turned out. Processing audio is not as simple as you would think and after working on Equalizer for 2 month I have more than high respect for the guys at INTUA.
However, working on coding audio manipulations was very enjoyable as it gave me another dimension of how making music is done and where the limitations are.
