Validating MP3 Compression Output
This section describes a tutorial on how to validate the compressed WAV file with MP3 (MPEG Layer-3) encoding.
If you followed the previous tutorial, you should have a WAV music file compressed with MP3 (MPEG Layer-3) format.
1. Using Windows Explorer to locate the compressed WAV music file: C:\temp\wav\02-Track 2-MP3.wav.
2. Click right mouse button on this file, and select properties. The properties dialog box shows up. The general tab displays:
File name: 02-Track 2-MP3.wav Type of file: Wave Sound Location: C:\temp\wav\ Size: 7,077,588 bytes
3. Click the Summary tab. It displays:
Bit Rate: 256 kbps Channels: 2 (stereo) Audio sample rate: 44 KHz Audio format: MPEG Layer-3
4. Double click on the file name: 02-Track 2-MP3.wav. Windows Media Player will be started to play this music.
If the WAV file plays well to the end, Sound Recorder did a good job of compressing a WAV audio file with MP3 (MPEG Layer-3) format.
