Course Details

Digital audio is a technology that is used to record, store and reproduces sound using audio signals which have been encoded in the digital form. With this training program, trainees will learn Signal to Noise Ratio (SNR), Nyquist Theorem, how SNR affects the quality of signal, Signal to Quantization Noise Ratio (SQNR), linear and non-linear Quantization, audio filtering and wave table synthesis. This training program educates trainees about Musical Instrument Digital Interface (MIDI), various hardware aspects of MIDI, understanding structure of MIDI messages and MIDI to WAV Conversion. Furthermore, trainees will get the knowledge of Pulse Code Modulation (PCM), PCM in Speech Compression, Differential Coding of Audio, Delta Modulation and Adaptive DPCM. There are no prerequisites for this course. This course is beneficial for both fresher and professionals to enhance their learning and skills.

FAQs

1. Are lab-sessions available after theory sessions?

We provide online lab facilities to all our students, wherever possible & applicable, using a combination of one or more options, including global ASP setups, live-environments, real-time simulations, training-videos, PPTs, Screenshots and others.

2. Who and how qualified are the instructors?

All our instructors go through a rigorous and multiple processes of filtering and selection before they are appointed by us. Only the most qualified, most experienced and best suited candidates are chosen as instructors.

3.What are the machine requirements for the course?

You must have a fairly good desktop PC or laptop. You can even access these courses on your tabs or smart phones. For PCs and laptops the configuration should be at-least an Intel Pentium processor, 4GB of RAM and 50 to 100 GB of free hard disk space. You must also have a good and steady WiFi internet connection which works at 3G or 4G speeds.

4.How will I undergo practical training in the course?

Depending on the type of lab facilities available for the course you have enrolled in for our instructor would be happy to help you in your lab sessions.

5.What is the process to get my questions/queries answered?

Get in touch with your trainer. You can also consult your batch-mates. We believe in collaborative and practical learning.

6.Can a free demo session be provided?

We do not provide free demo sessions.

7.Will there be a provision for repetition if I miss a class?

We encourage our trainees to attend all sessions. If you have missed a session we will try out best to update you on it, if possible. Else you will need to pay a small fee to have a repeat session arranged specifically for you.

8.Does your organization provide assistance in job hunting?

We are connected across the industry in India and abroad. We will pass on any job openings from our customer to our trainees. But we are not a manpower placement provider.

9.How and where can I make the payment?

You can pay using any credit or debit card in India or abroad. You can also pay using your PayPal account.

10. Will practice material or tests be also provided with the course?

Yes. As required & as applicable.

11.What is the minimum or maximum batch size?

Minimum/maximum batch sizes vary from course to course, depending upon a number of factors. It can vary from as few as 2 to as many as a few hundred, in some cases. But that number does not impact the quality of training that we deliver due to our tight quality-control mechanisms.

Certification

All trainees will be provided with a course participation and completion certificate by Aurelius Corporate Solutions. Please note, we are an independent provider of learning solutions. We are not affiliated in any manner to any company or organization.

Scope and Industrial Prospects

Digital audio is transmitted as a pulse wave, stored as a series of switches, magnetic pulses and looks nothing like the original pattern of changing air pressure. In the digital world usually numbers are used to represent a waveform. It offers repeatability and immunity to degradation, easy operation and automation, multiple functions in a single device, expandability and connectivity. It is a mathematical description of the pattern of pressure. Employers are looking for those people who have done this course on various jobs offering web-sites. With getting exposure to this training course trainees will get a high value addition to their skills and can get the job in top fortune companies. This course is more application focused as compared to theory focused in order to give the trainees a profound usability experience and procedures.
