How to get specific frequency and time values for .wav file

Click For Summary
SUMMARY

This discussion focuses on extracting specific frequency and time values from .wav audio files and exporting them as .csv files. Users have attempted to utilize tools such as Audacity, Sonic Visualizer, and SigView but require guidance on their effective application. A suggestion was made to use Wolfram Mathematica for extracting audio data, particularly from stable segments of the audio where frequency and amplitude remain constant. The goal is to analyze the audio's frequency, amplitude, and pitch over defined time intervals.

PREREQUISITES
  • Understanding of .wav file format and audio analysis
  • Familiarity with Audacity for audio editing
  • Experience with Sonic Visualizer for visualizing audio data
  • Basic knowledge of Wolfram Mathematica for data extraction and manipulation
NEXT STEPS
  • Learn how to use Audacity for audio segment extraction
  • Explore Sonic Visualizer's features for frequency analysis
  • Study Wolfram Mathematica's audio processing capabilities
  • Research methods for exporting data to .csv format from audio analysis tools
USEFUL FOR

Audio engineers, music analysts, data scientists, and anyone interested in performing detailed frequency analysis on .wav files.

How to get specific frequency and time values for .wav file and export the values as .csv?

Problem: I need to analyze this music .wav file, particularly for its frequency, amplitude, and pitch over specific intervals of time.

Is there any easy to use software and steps I can take that can help me accomplish this?

I have tried audacity, sonicvisualizer, and sigview, but I am unsure how to utilize these softwares appropiately to achieve my specific goal.

Thanks in advance!

I would use Wolfram Mathematica.
 
If you can extract a ten-second audio clip where the frequency, or pitch which means the same thing, and amplitude isn't changing much and post that audio clip along with an image of the graphic equalizer showing the sound at that moment then someone might be able to take a few minutes to see if they could give you the amplitude for a few dozen or hundred frequencies making up that clip. That could be turned into a .csv file and you could see if that might be what you are looking for.

Or you could send me a message and describe a little more about what you are trying to accomplish and I would see if I could offer any ideas.
