### Re: Computer Sleuth: Identification by Text Analysis

Niharikka, Both ANN and PCA are numerical methods, so you would have to convert your inputs and outputs into numbers, usually between 0 and 1. Have you used these before? Do you know how to write programs, and if so, in what language? There are quite a few open source programs for both ANN and PCA, ...

Neuropyrox,

Welcome to software development! You can expect such slaps in the face on a more or less daily basis for as long as you write code. Don't worry, you will not only get used to it but will also derive all the more pleasure when things work as expected. It happend to all of us.

Good luck!

Hi Monsterbasher,

Here are some hints for python. You can change the link to use your favorite programming language. I would recommend Python if you are indifferent about that.

### Re: Ideas for Audio Compression-related Project?

moonlitknight, What about the python libraries? Usually doing it directly in a scripting language like python strips away complexity and allows you to be more focused on individual tasks. Have you had a look? In practice, most people would probably go with that instead of hoping that an application ...

moonlitknight, I have to say that I'm not an audacity expert nor even of audio files in general. Have you looked at the audacity forums (http://forum.audacityteam.org/)?

### Re: Ideas for Audio Compression-related Project?

moonlitknight, I think your project question tells you what your independent variable is, the compression factor you use most likely determines the sound quality of the music. If you need more independent variables, then you can use one or two of the other settings you can tweak when storing a compr...

sonroyaalmerol, This sounds like an excellent idea! Your description, though, is long, complicated, repetitive, and as a result difficult to understand.

moonlitknight,

What exactly do you want to compare? Sound quality (subjective)? File size (objective)? Something else?

Try something like:
