AudioResamplerate

Introduction

This is an audio resamplerate program for Linux,support PCM and WAV audio(mone or stereo),bits of each sample is 16 default.

Component

• log : print verbose/info/debug/warning/error message.
• iniparser : configure the parameters by config.ini dynamically.
• resamplerate : resamplerate your parogram.

Installation

$ git clone [email protected]:AnSwErYWJ/AudioResamplerate.git

Usage

1. If you modify the file of three components, compile three dynamic library of components :

   $ make iniparser
   $ make resamplerate
   

2. If you modify the source/resamplerate.c include/resamplerate, compile bin :

   $ make
   

3. Modify the config.ini to configure the parameters, input support PCM or WAV audio files, and output only support PCM audio files, such as :

   [audio]
   channels = 1;
   input_sample_rate = 16000;
   output_sample_rate = 48000;
   
   [path]
   input = ./audio/S16bit-LE-16kHz-Mono.pcm;
   output = ./audio/out.pcm;
   
   [type]
   input = wav;
   output = null;
   

4. Then,run the program with :

   $ export LD_LIBRARY_PATH=./lib:$LD_LIBRARY_PATH
   $ ./resamplerate
   

Environment

• Linux
• POSIX C
• Bash Shell

Todo

• [ ] Use TOML replace iniparser.

Reference

• log
• Secret Rabbit Code
• iniparser
• Convering 8/16/32 bits/sample array to floats-array
