Is it possible to upsample using software?

Resampling/upsampling may provide a different sound, but it is by no means more accurate or higher quality than the source material. |

When transients are clipped due to insufficient sample-rate, good upsampling algorithms can add the missing samples back-in, providing more dynamics and clarity to the transients. I and my customers have done lots of listening tests that verify this. It actually gets more clear, more dynamic and less harsh. You should try SRC and ASIO 47A SSE2 on Foobar. Steve N. |

Resampling to higher sampe rate doesn't increase perceived "sound quality," only resampling to 48000Hz avoids issues with certain types of hardware |

CPU usage has shot up though to about 26% from 0-1% on my 3400+ se**** so this will not be a suitible setting for listening to while gaming. If you are sceptical just download foobar and try it. I did. *I used songs for the deaf for testing by queens of the stonage as this has lots of faint background sounds that usualy come out as mush on crappy systems (like mp3 players with bundled headphones *shudders*) ![]() |

Definatly not just in my head though as I keep switching back and forth and listen to specific points. |
