Pocket RTA Pro is a real-time spectrum analyser for your Pocket PC. I like RTAs, and this one is particularly fully functional.
PocketRTA samples sounds picked up by the built-in microphone on the Pocket PC and then applies a Fourier Transform to the samples to obtain a frequency spectrum. The result is an accurate representation of the sampled sound broken down into its frequency components.
PocketRTA gives total control over input sample rate and FFT length, so you can tailor the display to your needs. Sample rates up to 44Khz allow frequencies of up to 22Khz to be measured. Various display modes include, linear narrow band, logarithmic narrow band, Octave, 1/3 Octave, 1/6 Octave, Sample, SPL and Spectrogram displays with ANSI A and C weighting curves. PocketRTA allows real-time magnification (up to 250 times) of a selected frequency range. The touch screen allows selection of the nearest FFT point giving a display of it”s frequency and decibel level. Up to 64 times averaging and variable decay settings allow more stable readings for fluctuating or unstable input signals whilst our unique noise cancellation system allows you to remove unwanted background noise.
New Features of the Professional Edition:
PocketRTA Pro features the ability to calibrate the display using a 1/3 Octave display in order to compensate for imperfections in frequency response of the internal microphone.
Another new feature is the ability to capture any input signal and overlay it as a reference for a live signal. Captured traces can be saved and later loaded as a reference or exported to ASCII text for use in packages such as Microsoft Excel. You can even take snapshots of the screen which are saved in BMP format.
PocketRTA Pro also introduces a Compare / Transfer mode which allows you to compare a captured input signal against a live trace. The difference between the two traces are displayed using a 0dB reference point making it ideal for calibrating EQ”s. A smoothing option has also been added (wide band averaging) to remove unwanted spikes and make the display more readable.
Another new feature is the ability to capture a peak trace over time. Again this can be saved or exported for use in external packages.
I’ve not had a chance to play with this as yet, but it looks like one of the most rounded RTA apps I’ve seen so far. At some point I will get around to trying it out and then I’ll post a review.
For me the two main platforms for mobile music making are:
But I have to admit that I know very little about other platforms and how they shape up. I know that there was a tracker for Symbian which I did write about ages ago, but I don’t know of very much else.
Also, I think that as Styletap takes off and allows more and more Palm applications to run under Window Mobile it will become easier to run everything in one place as it were rather than keeping and maintaining multiple platforms.
Windows is still developing and moving forward, although, not in leaps exactly, but Palm don’t seem to be doing too much of anything right now.
Sure ALP is coming along, but what will that do for existing applications? Will it bring in more developers? Will it bring new possibilities in terms of hardware from palm or ease of development from ACCESS? Will it mean that Linux music applications are easier to port over to ALP?
The other possibility is that Palm will kick off their own OS separate from ACCESS and ALP altogether.
So, what does the future hold?
I’ve been trying to get some of the miniMusic applications to run on StyleTap and I’m having lots of problems. Mainly with MixPad and SoundPad to be fair. Anyway, I’ve been in touch with the people at StyleTap, and I’m just waiting on a response. It would be nice if these apps could run under StyleTap, it would be great to have everything in one place.
I was looking at some of the other products from 4Pockets and found this.
Virtual Recorder is a personal voice recorder for your Pocket PC which works just like a good old fashion tape recorder. The program uses a ”true tape” mechanism which gives the ability to record over any portion of a previous recording, and is not limited to a simple append process.
One of the advanced features of Virtual Recorder is the ability to time stretch your recordings. This would allow you to listen to a full hours recording in as little as 30 minutes, without it sounding unnatural or like the recording had been speeded up.
This means that you can sample music and slow it down without affecting the pitch; allowing you to practice those difficult guitar solos or whatever!
The software also has a Cutting Room which allows you to splice recordings or remove unwanted sections. (Cut/Copy/Paste and Fade In/Out facilities are supported). Now that is quite advanced for a PDA application.
Well, I’ve finally upgraded my old HP Jornada 568 for a Dell Axim 51. I have to say it is fantastic. Apart from the fact that there is much more space for applications, and there’s two expansion slots, the speed is wonderful.
Of course I’m running StyleTap on there as well so I am loading on Palm apps to to see if I can eventually make this my sole music device.
Matrixsynth: Z4 Music and Griff – Pocket Samplers
I have to take out some time to do a decent review of Griff, but this is a good start. I never got Z4 Music. Perhaps I’ll get it soon?
