There are some examples from last year. en-us 2022-02-23 01:26:08 UTC 2022-12-05 00:52:01 UTC hello@padlet.com https://padlet.com/aminafisher/kki91j1tv9g334sy/wish/2062318835 The file format used for this audio was the AAC audio format. AAC adopts the lossy compression process therefore discarding any sounds that vast majority of people cannot hear- sounds that are low in volume and high in pitch. AAC therefore is a smaller file size as it is saving space using a lower bit rate whilst producing high quality audio due to its compression algorithm

MP3 is lossy compressed, hence, the original bit depth is reduced to remove data. Also, the file size is reduced. MP3 file formats are widely supported on different platforms, thus it compatible across devices.

MP4 was chosen because although it uses lossy compression techniques, the process results in smaller file sizes and can be used on multiple platforms.]]> 2022-02-25 00:49:36 UTC https://padlet.com/aminafisher/kki91j1tv9g334sy/wish/2065538084
