LAME ENCODE PCM TO WAV CODE
The following code shows the simplest way to use the MP3 compressor with the default configuration: Within this library, I included all the translation of structures, constants, and functions needed to use lame_enc.dll.

All other classes related to the MP3 compressor are in a library yeti.mp3. Using the codeĪudioWriter and other base and tools classes are in a library named yeti.mmedia.

AudioWriter receives audio data in PCM format, then the data is compressed and written to the resulting stream, or just written without modifications using a specific format (WAV format, for instance, as in the WaveWriter class). The compressor I describe in this article ( Mp3Writer) is a class derived from AudioWriter, which is a binary writer that can be used as a base of writers for different audio streams (different audio formatters, compressors, etc.). One problem to mention about the use of the DLL is that in the current version, it is not possible to compress two streams at the same time. This DLL exports a few functions and it is relatively easy to use. However, an easier way to achieve that goal is to use the LAME compressor through the functions exposed by the lame_enc.dll. While it is true that the LAME encoder is written in C and all source code is available, one could think of compiling these source files in managed C++ to obtain a managed compressor. In this work, there is code from the article: A low level audio player in C# by Ianier Munoz. See this website for technical and copyright information regarding the LAME project. The solution was to use the LAME MP3 encoder, specifically to wrap in C# the functions of lame_enc.dll. NET framework and I couldn't find the exact solution, so I decided to write one.

Then I looked for some MP3 compressor done for.
LAME ENCODE PCM TO WAV HOW TO
The first question to my previous article ( C Sharp Ripper) was about how to rip directly to MP3 format.
