If you're using Windows, try downloading the shareware version of GoldWave
It allows to do some cool effects and to save files in MP3, reducing the file size.
Also try reducing frequency or converting from stereo to mono.
Guys just a heads up I am going to be shutting the site down soon. I am just waiting on the NUON people to decide whether they want to transfer forum data and keep the discord. My email is [email protected] for anyone that wants to keep in touch and I have a facebook too. I will make an official post later. Love you guys and will miss everyone!
