DTMF decorder from computer microphone

Job ID: 37539498

Budget: ₹1,500 – ₹12,500 INR

Project Overview:
Our objective is to develop a DTMF decoder capable of analyzing audio input from a web browser microphone, identifying Dual-Tone Multi-Frequency signals, and delivering a robust and efficient solution for seamless integration into our application across various use cases.

Key Objectives:
DTMF Signal Detection (Client-side using HTML and JavaScript):

Develop a real-time algorithm for detecting and differentiating DTMF signals (0-9, *, and # keys).
Ensure precise recognition of individual tones and combinations, displaying them on the page if multiple keys are detected (e.g., 1122345*#).

Microphone Integration:
Utilize the web browser's HTML5 microphone as the input source for DTMF signal processing.
Implement noise reduction techniques to enhance signal clarity.

Real-time Processing:
Achieve low-latency processing for real-time analysis of incoming audio streams.
Optimize the algorithm for optimal performance and efficiency.

User Interface:
Design a simple and intuitive user interface facilitating user interaction with the DTMF decoder.
Include features such as signal visualization and real-time feedback.
Compatibility:
Ensure compatibility with major browsers and desktop/mobile operating systems.
Provide clear documentation for seamless integration into our existing application.

Testing and Validation:
Implement a robust testing strategy to validate the accuracy and reliability of the DTMF decoder.
Conduct thorough testing with diverse DTMF signal sources and under various environmental conditions.
Error Handling:

Implement error-handling mechanisms to address potential issues, such as incomplete or distorted signals.
Deliverables:
Source Code:
Provide well-documented and modular source code in a programming language, preferably using jQuery, HTML5, Vanilla JS, or any relevant JS library.
Include comprehensive documentation and comments to facilitate integration into our project.
User Interface Design:
Design a straightforward interface featuring a button to initiate the microphone and begin listening continuously without causing system interruptions.
Timeline:
Please present an estimated timeline covering development, testing, and delivery of the DTMF decoder. Take into account potential challenges or dependencies that may impact the project timeline.
