Hi
I'm Gerard Grey, based in South East Cornwall. I develop web, desktop and phone (Android) apps. For recent examples of some items I have put together, check out the links under "audio" above for some interactive HTML5 sound and music apps.
WebAudio demos
Loopslicer is an app for chopping up drum breaks or other short musical phrases, typically used to decompose a bar or two of drumming into separate "hits." The slices can be exported to a ZIP file along with a SFZ sampler file and a MIDI file retaining the timing and tempo information of the original musical phrase.
This phase vocoder can change the time or pitch of any audio file loaded into it independently, so you can change the pitch without changing the speed or vice versa. Phase vocoders are used in musical production and transcription, voice-changing pranks, etc.
FFTGate Denoiser is a result of my experimenting with various tweaks to the FFT (Fast Fourier Transform) denoising algorithm. Load up the source code in your browser and/or email me if you really want to know the details of the tweaks.
Multifreeze is a "spectral freezing" effect for isolating a small fragment of a sound and turning it into an ambient texture. The app splits the audio into 24 frequency bands that you can freeze and free again ad libitum.
Other items
A web app for morphological analysis at https://kernow-ged.github.io/zwicky-morphological-analysis/. Based on the work of Johannes Buchner, who did all the real hard work here. I just added a few things to do with data presentation and export.
For magicians: a couple of very old magic apps of mine are now open sourced and available on Github.
(More open source works at https://github.com/kernow-ged.)
Services
I develop front-end and/or back-end web applications in a number of languages including Javascript, PHP and Python. If you need a standalone Android phone or tablet app, or a Windows-based desktop application developing, also do not hesitate to contact me for a discussion and quote. I use a variety of different methods to build native apps including Java, C++, Python, to name a few. I work in strict confidentiality and your ideas are safe with me.

If you are contacting me about development work, here are a couple of points that you might want to consider first:
- Do you already have access to resources such as domain names or server space that you wish to employ for the project? If not, do not worry. I will set this crucial infrastructure up for you. If you are not sure whether this will be required I'll let you know. When the work is completed I will need to pass on any online resources to the client. There are ongoing running costs associated with domain names, servers and cloud computing resources, over and above the setup, that you may need to budget into a project.
- Have you existing materials such as graphics, photos and text content that you need to incorporate into any work? Alternatively, do you need to source any such content? You may need to budget for this too.
