LameVST

MP3 encoding can have a noticeable impact on the quality of an audio file, especially if a very low bitrate is used. Naturally, file size limitations often make encoding mandatory, but it is normally only possible to ascertain how much quality is affected after the project has been finalized.
LameVST is a very helpful VST plugin that enables you to preview these effects in real-time, making it possible to reproduce the artifacts caused by low-bitrate MP3 encoding.

Relatively simple VST plugin that can be deployed easily

As you can probably imagine, an audio mixing application that supports VST plugins is required in order to use this tool. We were able to install and test it quite easily, so even novices should not run into any issues.
The plugin features a minimalistic GUI and includes a very basic of controls, making it a great addition to an already extensive tool set.

Simulate MP3 encoding using a VST effect

Once loaded, LameVST applies an audio effect that mimics MP3 encoding, allowing you to determine how sound quality will be affected once the file has been processed.
It is possible to select any bitrate from 16 kbps to 320 kbps, as well as switch between stereo and joint mode. While most users will probably not notice any change when using a higher bitrate, the negative effects become more and more noticeable as the value is lowered.

Preview MP3 encoding effects in real-time

No one wants to spend hours working on the perfect mix only to find that it sounds very different once encoded to MP3, and this plugin enables you to analyze the potential side-effects before the project has even been finalized.
LameVST allows you to avoid having to render your work multiple times in order to examine the results of MP3 encoding, and it can also help you fine-tune your mix so as to minimize the negative effects of data compression.
