Procedure TForm1.Button1Click(Sender: TObject) In this Audacity video tutorial, I will show you How to Install LAME MP3 Encoder. His goal was only to speed up the dist10 sources, and leave its quality untouched. After some quality concerns raised by others, he decided to start from scratch based on the dist10 sources.

Mike Cheng started it as a patch against the 8hz-MP3 encoder sources. Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls Latest LAME release: v3.100 (October 2017) LAME development started around mid-1998. System.Classes, Vcl.Graphics, bass, bassenc, Unfortunately, it is a command line utility, and that is where RazorLame comes in. LAME is a great MP3-Encoder: it's very fast, it produces high-quality files, has many advanced features (like Variable Bitrates and Joint-Stereo), and it's open source. Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, RazorLame is a so-called 'front-end' for use with LAME. To use sample code put a listbox ,opendialog and two buttons on form unit Unit1

Put bass.dll ,bass.pas,Bassenc.dll,bassenc.pas and lime.exe in same folder as your project exe file. You can do this using bass ,Bassenc and lame encoder. For better peformance the expression outsamples := insamples1 shr 1 + insamples2 shr 1 could be used instead.įor an approach maximizing both, performance and audio quality, I recommend this post, it basically propose using the following expression (A and B are 0-1 normalized audio samples): Z = 2♺♻ if both A<0.5 and B<0.5 It would be something like: outsamples := insamples1/2 + insamples2/2.

In both cases, you will need to go over the audio samples of both files, treating each channel independently, and averaging the values from input1 and input2 in your output file. LAME is a great MP3-Encoder: its fast, it produces high-quality files, has advanced features (like Variable Bitrates and Joint-Stereo), and its open source. There are Delphi header files for Directshow in a package called DSPack.įor producing an mp3 file as result of overlapping the sound from the two input files, you will need to decompress the two audio files, do the mix and recompress them again. Directshow could also be used for this task.
