higher sampling

[finnind]

After downloading NIN new album on their homepage I found out that my new Arcam music server was not able to play 24bit 96kHz files. After a little playing with dbpoweramp I found out that my my music server can play 16bit 192kHz files which I think sound great.

How come I came sample a music file with a higher sampling than it original was?

Is dbpoweramp guessing and put some extra data into the files. If dbpoweramp is just guessing isn't wrong of me to do so. Wouldn't it be better if I just left the sampling rate at the normal frequency?

Am I able to do the same with a redbook cd. Sample it to 16bit 192kHz?

Re: higher sampling

As sound is sine waves, it is possible to increase the sample resolution, but you are not gaining any higher frequencies.

Thank you for your reponse.

So you are saying that dbpoweramp is increasing the amplitude of the sinwave and that is the differences I can hear when I raise the sampling frequency from 96kHz to 192kHz?

When I raise the sampling frequency artificial with dbpoweramp does it have any negative effekts?

Will I be able to raise the frequency from 44.1kHz to 96kHz or 192kHz on a redbook cd with a good result?

When you are saying I'm not gaining any higher frequencies. Is it overtones you are thinking about. If the original sampling rate is 96kHz there must some overtones is that correct.

Re: higher sampling

Sorry my wording was a little off, it should be 'increase sample rate'

The amplitude stays constant, consider a simple sine wave, draw it by pen and mark dots on the line every centimetre that can be 44KHz. If you double the dots on the line that is 88KHz, so it is possible to change the sample rate, but going between sample rates is a lossy process (a small amount of quality is lost), but it might give better playback depending on your audio hardware.

Make sure the professional frequency conversion option is enabled in dBpoweramp configuration and that you use R13.4 from the beta section as this contains fixes for 192KHz conversions.
