Title: How to Determine the Real Quality of an Audio File
Channel: Facundo González
Description: Have you ever had a high-quality audio file (e.g., mp3 at 320 Kb/sec) but felt like it sounded lower in quality? In this tutorial, we will use a program called Spek (downloadable from http://spek.cc/) to analyze the audio spectrum of the file and verify its quality. I will also provide a table with approximate values that Spek displays and their corresponding audio quality levels.
Summary Overview: In this video, Facundo González demonstrates how to use the Spek program to analyze the audio spectrum of an audio file and determine its quality. By examining the frequency cutoff points in the spectrum, viewers can assess the audio quality level of the file. Facundo provides a table with approximate values and their corresponding audio quality levels to help viewers interpret the results obtained from Spek.
Tutorial Instructions:
-
Download Spek: Visit http://spek.cc/ to download the Spek program onto your computer.
-
Open Spek: Launch the Spek program on your computer.
-
Load Audio File: Select the audio file you want to analyze within the Spek program.
-
Analyze Audio Spectrum: Use Spek to analyze the audio spectrum of the selected file.
-
Interpret Results: Look for the frequency cutoff point in the spectrum to determine the quality level of the audio file based on the provided table.
-
Quality Assessment: Compare the frequency cutoff point with the values in the table to assess the audio quality level. For example, reaching 22 KHz without abrupt cutoff indicates CD quality, while lower frequencies correspond to lower quality levels.
-
Further Questions: If you have any doubts or questions about interpreting the results, feel free to leave a comment for Facundo González.
By following these steps, you can effectively use the Spek program to assess the real quality of an audio file and ensure that you are experiencing the best audio experience possible.
