What are the two types of audio processing?

There are 2 types of audio compression exist, i.e., lossless and lossy compression. The most widely used audio compressions are lossy methods due to their much larger compression ratios than their original data. It can eliminate the information that is not very relevant and any decline in the quality.

What is a block in audio?

A audio block is an array of floating point numbers representing audio.

What is block processing?

In block processing, a block of output samples is computed for each input block, which results in a large delay between input and output. Block processing is commonly used for DSP algorithms based on matrix operations, but it can also be used to increase the maximum sample rate.

What is meant by audio processing?

Audio signal processing is at the heart of recording, enhancing, storing and transmitting audio content. Audio signal processing is used to convert between analog and digital formats, to cut or boost selected frequency ranges, to remove unwanted noise, to add effects and to obtain many other desired results.
