Frequency Sweep 0hz- 50,000hz 200 hz intervals

post #1 of 9
Thread Starter 
Forgive me if this is the wrong forum but I figured it has to do with computer audio. I'm looking at getting a hold of a single audio file containing 0hz-50,000hz. I download and installed quite a few programs but they all seem to be limited to 20,000hz. Is it possible someone can make me a quick file with the specified frequency sweep? I'd really appreciate it.

How long should the sweep be ?

Well, here is a one minute sweep at 192 kHz sample rate, the frequency increases in 200 Hz steps from 0 Hz to 50000 Hz.

That's awesome.Thank you so much. I'm thinking I might need it longer. I'll let you know though.

Just listened to it. Nicely done. Can you make one from 0hz - 5000hz and transcode it in both .wav and .mp3?

What should the length and intervals be ?

I apologize for taking so long. My computer is currently giving me a HDD error. 

 

200hz intervals

OK. Should the length be 1 minute again ?

Here is a 59.8 seconds sweep that you can generate with the "testgen" utility from the package at the third link in my signature. Just copy and paste this to a plain text file:

 

sine  0.0 2.3    0 0 d-3 d-3
sine  2.3 2.3  200 0 d-3 d-3
sine  4.6 2.3  400 0 d-3 d-3
sine  6.9 2.3  600 0 d-3 d-3
sine  9.2 2.3  800 0 d-3 d-3
sine 11.5 2.3 1000 0 d-3 d-3
sine 13.8 2.3 1200 0 d-3 d-3
sine 16.1 2.3 1400 0 d-3 d-3
sine 18.4 2.3 1600 0 d-3 d-3
sine 20.7 2.3 1800 0 d-3 d-3
sine 23.0 2.3 2000 0 d-3 d-3
sine 25.3 2.3 2200 0 d-3 d-3
sine 27.6 2.3 2400 0 d-3 d-3
sine 29.9 2.3 2600 0 d-3 d-3
sine 32.2 2.3 2800 0 d-3 d-3
sine 34.5 2.3 3000 0 d-3 d-3
sine 36.8 2.3 3200 0 d-3 d-3
sine 39.1 2.3 3400 0 d-3 d-3
sine 41.4 2.3 3600 0 d-3 d-3
sine 43.7 2.3 3800 0 d-3 d-3
sine 46.0 2.3 4000 0 d-3 d-3
sine 48.3 2.3 4200 0 d-3 d-3
sine 50.6 2.3 4400 0 d-3 d-3
sine 52.9 2.3 4600 0 d-3 d-3
sine 55.2 2.3 4800 0 d-3 d-3
sine 57.5 2.3 5000 0 d-3 d-3

 

Then run the following command (sweep5k.txt is the name of the text file, and 48000 and 16 are the sample rate and bit depth; change these as needed):

 

testgen.exe sweep5k.txt sweep5k.wav 48000 16
