In my app I am recording voice using AudioRecorder as given in the following site, Audio Recorder it is working but it produce large size WAV file.
For example : If I record audio for 1 minute it takes 4MB to 5MB. So that I want to convert the wave file into MP3 file to reduce the size of the file. Please help me to compress the wav file ,give some example. Thanks in advance.
I never tried converting files before so i looked up on some threads that might be helpful to you.
One is converting wav to mp3 which require file conversion into a byte[]
public byte[] ConvertToMp3(Uri uri)
{
using (var client = new WebClient())
{
var file = client.DownloadData(uri);
var target = new WaveFormat(8000, 16, 1);
using (var outPutStream = new MemoryStream())
using (var waveStream = new WaveFileReader(new MemoryStream(file)))
using (var conversionStream = new WaveFormatConversionStream(target, waveStream))
using (var writer = new LameMP3FileWriter(outPutStream, conversionStream.WaveFormat, 32, null))
{
conversionStream.CopyTo(writer);
return outPutStream.ToArray();
}
}
}
however on this method he is using a third party service which downloads the wav file and then to be called on that method but this does not guaranty if the file size will be reduced.
however i have check that you can compress wav files using a library called zlib. just decompress it whenever u need it.
