Overview |
WAV or WAVE is an audio format which was developed to store audio files on personal computers. These files include music, spoken or speech audios and sound effects. The size of the files in this codec is very large as it does not use a lossy format like MP3. This is the main reason why this format has lost its popularity. Due to its size, it is hard to transfer files over the internet which had resulted in less acceptance. This format is supported by many programs like a window Media player. Therefore, these audio files can be played using aforesaid software. One can not completely ignore this format as it provides high quality of audios. Due to this, it is used for radio broadcasting. |
Technical description |
This format supports metadata that is why we can add details using information chunk. Data in this codec is stored in chunks as it is an application of RIFF(Resource interchange file format). Furthermore, LPCM(Linear pulse code modulation) is the most common, uncompressed audio format in this, but it can also store compressed audio like MP3. Also, it is especially used by professionals as LPCM audio format offers a maximum quality. Only files up to 4 GB are supported by this format which is one of the limitations in this format. This is because of 32-bit unsigned integer which carries the file size header. To overcome this, W64 format came into existence which can record long audios as it enables 64-bit header. |

Overview |
It is a format for audio files which compresses the audios using lossy compression. It neglects the redundant information which can not be processed by the human ear. Internet Engineering Task Force (IETF) has standardized this format. It has superseded the Vorgis and Speex. It offers low latency i.e. there is a less delay in the signal when it enters the system and when it emerges out, this results in real-time interactive communication like video conferencing. Due to its good audio quality, it is widely used by in various listening tests. |
Technical description |
OPUS has good compatibility with low-end embedded processors as it is less complex. Ranging from 6kbps to 510kbps, it can support both variable and constant bitrate coding. Also, the frame size from 2.5ms to 60ms is supported by this codec. It works smoothly and maintains stability (by avoiding the distortion) while mixing of packets from distinct streams. Speech, Hybrid and pure-CELT are the three different methods used for encoding the audios of varied frequencies. For compressing the Speech up to 8kHz, SILk is used which is an audio compression developed by Skype Limited. The next mode, Hybrid uses CELT to compress the audio files above 8kHz frequency or for wider bandwidth and frame sizes 10ms and 20ms are supported by this mode. CELT(Constrained Energy Lapped Transform) is an open and free audio compression format which is especially used in communication that requires low latency. For general audio, the last mode pure-CELT is used. CELT is used for frame sizes which are less than 10ms. |
