Convert WAV to MP3

WAV is one of the most common audio formats and stands for Waveform Audio File Format. It is intended for operation with a digitalized audio stream. However, it has also been used for non-audio data due to its sampling rate (1 Hz to 4.3 GHz). It contains musical compositions, voice recordings, and various audio effects. Developed by programmers from Microsoft and IBM, it is a crucial audio format for placing uncompressed sound files on Windows PCs. The wav wave files can be played back in QuickTime, Windows Media Player, Wav Player, and some other programs. In addition to that, they can be processed in audio editing apps.

When a file is compressed into WAV, the data are not supposed to be lost, and the quality is excellent. However, the format did not have a considerable market share due to its larger size than MP3. It must have enough time and disc space to upload and send such files via the Internet. One of WAV's major advantages is linked to Linear Pulse Code Modulation (LPCM) to store an audio stream. Consequently, a copy is just as good as an original, highly appraised by experts in music and professional users.

Sound files with this extension are recorded into 8 or 16 bit per sample. A standard option for CD Audio is an audio stream of 16 bit per sample and a sampling frequency of 44.1 KHz. One second of sound corresponds to 88 Kb of internal memory. WAV files can store metadata in the INFO chunk, and they also include integrated IFF lists.

In some cases, the standard format may be used for broadcasting. For instance, BBC stereo data of 44 100 Hz and 16 bit are generally accepted within the VCS system.

MP3 (formally MPEG-1 Audio Layer-3 or MPEG-2 Audio Layer-3) is a digital format for storing audio files and audio streaming. MPEG programmers designed the format. It is one of the most required codecs for digital coding. The format is widely used in various file-sharing sites for evaluation downloading.

Due to lossy compression in this audio format, it is possible to compress CD tracks up to 1/10 of their original size while maintaining high playback quality. Moreover, it can be encoded at higher or lower bit rates to adjust the resulting quality. Overtones, which cannot be perceived by a human ear, are removed. Complex algorithms allow for a smaller size of tracks. As a result, one compact disk can contain several hundred songs. MP3 is compatible with all the most popular operating systems and is supported by most modern DVD-players and music systems.

Before MP3 introduction, MPEG-1 had been widely used. That format contained not only audio data but images as well. MP3 breaks an audio file into parts of the same length. When the processing is over, each part is packed into its frame. It involves the spectral limit technology that requires a continuous input signal to provide the use of two adjacent structures.

When spectral deleting is over, the file is to be compressed with mathematic methods. If necessary, the compression rate can be changed, even inside the same frame. Files of 128 kbit/s have 11-fold compression. Further reduction of the file size will lead to a significant deterioration in sound quality.
