Analysis of problems faced in Audio

Overview of Audio Coding:

Certain principles that are followed during audio coding are:-

--- Basic redundancy removal
--- Amplitude range and segmentation
--- Multiple channel redundancy
--- Prediction
--- Entropy coding
--- Numerical implementation and portability
--- Segmentation and Resynchronization
--- Variable bit-rate:- Peak rate vs Average rate
--- Speed and Complexity

Understanding audio coding mechanism:

(a) Audio Encoding Level
Step 1: Analysis of fliter-bank through perceptual model.
Step 2: Then, it proceeds to Quantization and coding through analysis and perception of filter-bank.
Step 3: This is followed by encoding of Bitstream.
(b) Audio Decoding Level
Step 4: The decoding of bitstream is processed.
Step 5: This is followed by the Inverse Quantization.
Step 6: Finally, the synthesis of filter-bank.

Understanding audio speakers behaviour:-

The human ears gets interpreted as sound while the air molecules gets pushed and pulled in the form of waves, which is experienced in audio speakers (or loudspeakers).

The audio speaker consists of the following parts starting from exterior namely,
--- Surround
--- Dust cap
--- Cone
--- Spider
--- Basket
--- Former
--- Winding
--- Voice coil
--- Terminals
--- Top plate
--- Magnets
--- Pole piece

How audio signal flows through and out of the voice coil?

The signals hit through the voice coil, where a magnet is made by electric current is called as an electromagnet. Then, it gets suspended inside a ring-shaped permanent magnet.

Connecting to web:

The audio speakers is connected through port and the device hardware is enabled. While uploading any audio by means of recording, then heavy audio sampling signals are passed leading to requirement of heavy network bandwidth and speed to make it work, which occurs as a challenge.

Analyzing the issues faced during audio coding:-

The audio issues are analyzed during live radio and live audio webinars where we get buffering suddenly in the middle, which could be sometimes a problem from the response while the request gets the issue. There are also problems occuring during audio communication between two people, where the sampling signals gets broken at times.
