If double-digit compression is your goal, lossy codecs are the only way to go. Even if lossy compression artifacts exist, they might be inaudible. Song clips of similar duration from different music ...

There are two categories of data compression. The first reduces the size of a single file to save storage space and transmit faster. The second is for storage and transmission convenience. The JPEG ...

Data Compression is one of the most important components of this world, driven by petabytes of data daily. We, as humans, are generating data every second. From walking to running, eating to drinking, ...
