Let’s modify the command to change the audio bitrate: $ ffmpeg -i sample.mp4 -c:v libx264 -c:a pcm_s16le -b:v 1200k -b:a 192k output.avi. The -b:a option specifies the audio bitrate. The command above outputs the output.avi file, which uses H.264 video codec with 1200 kbps and PCM audio with 192 kbps. 5. AC3. AC3 is an audio file format that uses Audio Codec 3. Dolby Digital developed AC3 that gives a surround sound experience. It is mostly used in DVD or Blue-Ray disks. It supports 6 Channels music and can provide 6 different sound effects.

MP3 (MPEG Layer 3) is a digital audio compression format that is currently the most popular audio format in the world. The appearance of this type of audio file can be called a small revolution, because .mp3 files have a very high compression ratio while maintaining excellent sound quality, and it also uses a very complex mathematical algorithm for encoding a file that does not look like WAV (hi-res): The standard format all CDs are encoded in. Great sound quality but it's uncompressed, meaning huge file sizes (especially for hi-res files). It has poor metadata support (that is, album artwork, artist and song title information). AIFF (hi-res): Apple's alternative to WAV, with better metadata support. HDconvert 2012-2024. Convert audio to MP3 format to high quality sound and with high audio bitrate without file size limit.

The MP3 contains bits of digital noise and compressed sound files. The WMA file contains compressed sound files like MP3. While the WAV file contains data encoded with LPCM , ADPCM. This can even contain MP3 encoded data. WAV and AIFF: Both WAV and AIFF are uncompressed formats, which means they are exact copies of the original source audio.The two formats are essentially the same quality; they just store the data gkVDV6.
