Upscale MP3/Audio with ffdshow

Many people do ask me how to improve audio quality with ffdshow audio. Well thankfully there is a simple way to “upscale” the audio to an acceptable quality especially if you have a good set of speakers and not to mention a dedicated sound card. When I mention dedicated sound card , you need to be using a 24-bit PCI Soundcard such as Creative SoundBlaster otherwise its a no go. Onboard cards such as Realtek are unable to upscale the audio properly. So lets get started first shall we.
Requirements :-

  • ffdshow installed (prefberly  latest version) – If you don’t have one , I would recommend you to use K-Lite Codec Pack
  • A player which supports ffdshow (DirectShow Filter) such as Media Player Classic
  • A good set of 2.1/4.1/5.1/7.1 speakers. You may forget about it if you’re planning to use it with a cheap set of speakers.
  • A dedicated sound card. Preferably SoundBlaster Audigy or X-Fi series. Other similar cards would work. However , I wouldn’t recommend you to use onboard audio cards such as Realtek sound card!

Firstly fire up the ffdshow audio show decoder settings. It can be found under ffdshow or K-lite codec pack under programs. Now head over to Resample and configure it as shown below

Now after that head over to the Output section and uncheck 16-bit and select 24-bit. This is very important , make sure you have a 24-bit capable sound card. Onboards are capable of doing 24-bit , by doing soo , you’ll be adding more noise and they’ll just take more of your CPU Usage. I highly recommend you to use a dedicated sound card at least.

Well thats about it. Listen to your same audio again and do notice the improvement. I am sure that you’ll start to enjoy the great improvement of the audio quality. This is the way on how I’ve managed to upscale my 128Kbps-320Kbps MP3 to a la CD-like audio quality. Its free by the way
