Hi all.

As I told while I introduced myself, some time ago, I’m totally blind and I use computer throughout screen reader and braille display.

I’m looking for a good and fine tuner, as I’m a beginner student of music. All the tuner I found have graphical output and therefor they are not accessible to my assistive technologies.

The only one I’ve found is called talking tuner and it runs under iOS.

By the way I think it could be pretty easy to program a simple tuner using CSound.

I need a script that listen to the microphone and, each 10… 20 seconds or so, prints out to the console or prompt, the closer note detected, the + or - correction to that note, the octave which that note belongs and the detected frequency in HZ.

Do you think it would be difficult to reach?

Do you know if something like this already exist somewhere?

Many thanks.

Gabriel.

No, It would be useful to have it running under windows and MacOS, where I have the finest microphones.
The script should have the most simple output possible: no graphics at all, just one line of characters like:

Detected: A4, +13, 453HZ

Each line should be delayed on time by several seconds, in order to give the user, time to read it in braille or using voiceover output.

Here is an example. I haven't tried it out with live audio yet as I am in a library at the moment. There are two global variables near the top of the orchestra: one that defines the time gap between printings and one that defines an amplitude threshold. When the input signal is below this threshold printing will be skipped. You might like to adjust these values.

Let me know how you get on with it.

Regards,

Iain

I guess you should try some of the pitch tracking opcodes and see which give you the best results. you can print any strings from Csound using the print opcodes, and you can set up a metro to time the printing. 

Ok.

I’m an absolute beginner with CSound.

Can you give me an example of the opcodes to track the pitch, and how to set a metro in order to execute a timed command?

Thanks.

Gabriel.

I was tempted to test it out properly but was worried about the strange looks I might get from fellow library patrons as I started humming into my laptop...

This is amazing Iain, you're actually in a library?!
