Comprehensive Report: Audio Streaming Technologies, Services, and APIs

This report provides an introduction to audio streaming, detailing its core concepts, technologies, and applications. It begins by defining audio streaming and explaining its reliance on network protocols and buffering systems. The report then discusses sound quality, highlighting bandwidth requirements and the impact of data compression methods, particularly MP3 encoding. It outlines the three key processes involved in audio streaming: digitization, encoding (compression), and marketization. The report further explores the mode of operation, the five steps in the streaming process, and the benefits of audio streaming as a marketing tool. It also covers various applications, including B2B/B2E, B2C/C2B, and C2C/P2P scenarios, and explores the role of APIs in real-time audio streaming services. The report provides examples of audio streaming services with APIs, such as Spotify and Deezer, and describes the API's role in controlling software functions. The report concludes by outlining the API's process including running commands, testing execution, and monitoring commands. It also mentions the AudioStreamingFramework and its Java packages.

Introduction to Audio Streaming
Audio streaming is the method of distributing real-time audio through a network connection.
This type of data transmission requires certain protocols for handling the chronology of data
packets or other transmission types.
Audio streaming uses a secure data stream platform and a buffering system to listen the full
audio files without interruption. It also requires significant bandwidth to transmit the audio files.
It enables a variety of "broadcasting programs and formats to access the music and sound
archives. Audio streaming using the internet radio, to solve a basic problem of broadcasting. For
broadcasts, only the frequency spectrum are suitable.
Sound Quality
The well-known streaming providers such as MTV, CNN and Tower Records has some
technical quality of the sound. These streaming providers are valuable than the DVD, TV and
CD quality. In audio streaming, the range of network bandwidth from 10 to 100 mbps or higher
to allow high quality audio streams. The quality losses of internet streaming blamed by keynote
in the year 2000.And also reach a sound quality that is easy with the simple FM radio.
Data compression
We reduce the data volume of audio streams and files by the data compression methods as well
as data reduction methods. This compression is only suitable for mp3.Even the distracting
distortions are audible on certain tunes at 128kbps in mp3 file. So encoding the mp3 file at
192kbps or higher is enough to the compression processes.
Technology
There are three processes to streaming the audio. They are
 Digitization
1

 Encoding (compression)
 Marketization
Mode of operation
Process of streaming audio has the following five steps:
 Pre-production
 Production
 Distribution
 Playback
 Analysis
Benefits
 Audio streaming is popular across the world as a marketing tool.
 By using the audio, we create social awareness and sell something on the website. Not
only for the websites and also used in webcasts and e-brochures.
 It is much cheaper to make and broadcast.
Area of applications
The applications of streaming video is given below:
 B2B/B2E-for the web conferencing and web presentations.
 B2C/C2B-for the online advertising such as brand extensions and rich media ads.
 C2C/P2P-for the instant messenger and chat.
 Internet Telephony
Real-time audio streaming services with API

API is an acronym of Application Programming Interface. API can defined as a bunch of
operations. It is very useful to the developers. This API helps the developers to save the time.
Hardware and software resource access will be controlled by API’s. It can control the access of
some software functions. Because that software doesn’t have permission to access that
application. An API is also called as a messenger. That ensures seamless functioning and
processes request of enterprise systems. It is used to generate interaction between applications,
data and devices. It is also used to describe the connectivity between programs and devices and
API has the ability to deliver the data. It allows some of the applications to get communicate
with backend servers. It is also done by API. But this API allows only a limited amount of
program’s internal functions. Some of the audio streaming services with API’s are Spotify and
Deezer.
Spotify
Spotify is one of the audio streaming services. It provides more flexibility. Because it helps to
easily accessed the data and devices. It is the high quality audio streaming services. Audio
streaming ranges will be varied. There are,
High quality streams are at 160kbps
Extreme quality streams are at 320kbps
Normal streams are at 96kbps.
Here API is run as a backend server.
Deezer
It is also one of the audio streaming service. This service is based on internet. It helps the user to
listen the audio content with the recorded labels. Streaming services provided by both the online
3

and offline services. Here also the API will run at the backend server.
For users point-to-point audio streaming the sharp stream platforms will be used. Here National
and international radio networks use audio streaming FM broadcast for the communication.
Important process of API
Step 1: Run arbitrary commands in API
 Filter the running process
 Then redirect the output
 Connect heterogeneous commands for scheduling process.
Step 2: Test the execution commands
 At first run a series of tests
 Output will get logged
 Finally leftover process will be cleaned
Step 3: Monitor the commands
 Long-running process will be monitored
 If they get terminate then restart it
 Collect the usage statics.

AudioStreamingFramework is provided using which API is implemented. Java package got
AudioStreamingFramework, Packet and Block. AudioStreamingFramework gives setup ,
initialization and shutdown methods. Main program is designed to call these methods.Full work
is done in lossless mode and results obtained.
