Hello
A friend of mine was so kint to provide me with a sine sweep from 20hz
to 20khz lasting 60 seconds. It is a flac with 24 bits per sample and
96khz samples stereo. It was generated by csound and had some clicks
added every ten seconds so that I would know the file was still
playing.
It can be used to test speakers, ears and to generate impuls response
characteristics that could be helpful for room correction using inguz.
But 

*** WARNING *** WARNING *** WARNING ***

The energy of any given wave is proportional to its frequency meaning
high frequencies carry loads of energy that could :
- destroy the high tone driver of your speakers
- SERIOUSLY HARM your ears (gave me a bit of pain actually )
- irritate bat man and your dog.

Since high notes are generally perceived less likely by human hearing
there is a temptation to raise the volume of your amp or to move closer
to your high end speakers just to proove that the money spend for a
transporter dac of any kint amp or speakers wasn't for nothing. DO NOT
DO IT! I shall not be liable for any damage to you or your equippment!
Just keep the volume down and listen how long you can actually hear
something. The high frequencies have a longer duration since there are
more frequencies to itterate through than in the low range which is
just due to the fact that a linear algorithm was used.
Low frequencies are therefore under represented in subjective hearing.
Any reports about speakers transporter or sb3 performance are GREATLY
welcomed. If you want other files for example with exponential
itteration to have equal representation of low and high frequencies I
might ask my friend.
You can download the file here:
