The AudioCopy network

Monday, June 14th, 2010

iPhone apps are limited by the functionality that the iOS provides. They are also limited by the processing power of the device they run on. The iPad has way more ooomph than the original iPhone. Yet most apps have to run on all devices.

As for iOS: with the advent of OS3 almost all apps moved up to use the pasteboard.

It is the single most important secret weapon audio apps have to make sure mobile music creationists can compose on the go: it enables apps to pass on audio and receive audio.

Most audio apps are very specialized to do a certain task very well while only being marginally competent for other things. So in order to have good tools for all aspects of music creation, you will need apps that can talk to each other and pass audio on.

Last year Sonoma Wireworks introduced audiocopy and paste. At the time, I just finished my pasteboard for audio files. While my system did have a few advantages, I still felt that audiocopy was the better solution overall and decided to scrap my work to support Sonoma and prevent a split of the community.

Audiocopy copies wav files to the pasteboard. It also encapsulated information about the audio, like what app it is coming from, bpm, length and number of channels. The latest incarnation of audiocopy has a history of 12 files available so you can in essence copy 12 files from one app to many. The support of the general pasteboard is just icing on the cake to re-unify the split of the audio-app community.

That’s what I call the audiocopy network. It is an important stepping stone to mobile music. You should not buy audio apps that do not support audiocopy as those apps will always be inferior to the audiocopy network.

Need to move your audio from iPhone to your new iPad?

Thursday, May 27th, 2010

[** UPDATED ** see YouTube video below for demo]

I am talking about your audio files in Beatmaker, or Fourtrack or any other app that supports a pasteboard to interchange music between apps (for a more or less up-to-date list: General Pasteboard, Sonoma AudioCopy).
Consider using AudioView on both devices.

Will you upgrade to the new iPhone in June and want to avoid transferring all your music back to the computer via wifi and then onto your new iPhone?
Again AudioView is the solution. AudioView supports a protocol called audioX that enables two iDevices running an app supporting that protocol to exchange their music files directly. The two iPhones detect each other and display a list of available files. Selecting a file transfers it directly to the device.

On iPad, you have the choice of using Reforge and pair it up with AudioView on your iPod or iPhone. Of course AudioView works flawlessly on iPad as well.

Then what?
AudioView supports both pasteboards (general and Sonoma) which makes it a great fit for collecting all your audio in it and transferring it over.

What’s the catch?
Right now AudioView is only supporting file transfer one by one. BUT the good news: Work is in progress on a ‘transfer all files’ feature.

UPDATE: the get all feature is available now in AudioView in the app store. See it in action in the YouTube video below.

Follow @ibeatmaker on Twitter to get updates on progress and when it is available. Or check back here as I will update the blog when the ‘transfer all files’ feature is available.

Equalizer for iPhone

Thursday, July 9th, 2009

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. 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:

Equalizer in the iTunes store
Best iPhone apps at AppStoreHQ

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.

Part four of how I use BeatMaker

Tuesday, February 17th, 2009

Yes I know. It’s been more than a month since my last update. I did get things done though. Just didn’t have time to write home about it.

So I did work some more on the hiphop song. And after listening to it for more than two weeks on my iPod, I do like it.
I reworked the rhythm section in BeatMaker and exported the drums back to Reaper. There I adjusted the levels and applied a few filters both low and high pass (obviously to different tracks) to get the sound and feel I am looking for.

Mixdown and open it up in Ozone to equalize. This is for me a very lengthy process as I do it all on headphones and only get to listen to the mix on real speakers every other day (that’s just the reality of having a family life).
Once I am comfortable with the average eq curve and the sound, I’ll do some compressing of the drum peaks to get some more loudness out of the mix. I do prefer to have a larger dynamic range though so I am not compressing the heck out of it.
Well, this is pretty much it for now.
After listening to the song for over two weeks now, it really grew on me.

My interests are currently shifting a bit as I am learning to program for the iPhone and will have my first app in the store pretty soon. But that’s a posting for another day…
