Now, was that so hard?

A quick update.

1. PLUR: DoaR is dead. I killed it. Not enough time and it sucked, anyway.


2. I now run an Internet radio station, co-DJ'd with Kyo-sama. It's called SubLevel 21.

Now, this post is all about audio formats. Specifically, resampling. What I use on my server to broadcast is called sc_trans_linux040. Support is still experimental, but it works well enough. Now, a common problem with sc_trans is that it does not handle anything with a sample rate other than 44.1 kHz. I have some of my songs encoded at 48 kHz.
The error goes as such:

Warning: input file samplerate is 48000 Hz, must be 44100!

or

Warning: input file samplerate is -1209601104 Hz, must be 44100!

It was literally impossible to find a guide online of how to re-encode mp3s. So, here you go. Note that this guide requires a basic understanding of Terminal (or at least DOS).

1. Open your favorite Terminal application.


2. Enter in the following commands and let them run:
   
   
   
   • sudo apt-get install mpg123
   
   
   • sudo apt-get install lame
   
   


3. cd to directory containing the mp3.


4. Enter in the following commands (in order) and let them run:
   
   
   
   • sudo mpg123 -w <filename>.wav <filename>.mp3
   
   
   • sudo rm <filename>.mp3
   
   
   • sudo lame --resample 44.1 <filename>.wav <filename>.mp3
   
   

This process does not work on Windows. Why? Because Windows doesn't really use RAW audio for its wav files. It uses a proprietary audio codec that doesn't compress, similar to FLAC.
