![]() AAC’s were meant to be the successor to MP3 files, but did not catch on as a replay format. AIFF is a file format developed by Apple to be used on Mac OS much like WAVE files were initially developed by Microsoft. Other file types include Audio Interchange File Format (AIFF), raw Pulse Code Modulation (PCM) data, and Advanced Audio Coding (AAC). mp3 files best when you need fast streaming. wav files great for when you need the highest quality audio and. The most common audio data file types are. However, computers can represent that data in many ways. There’s one well known way to represent sound - using waves. Some common sampling rates are 16 kHz (common for VoiP), 44.1 kHz (common in CDs), and 96 kHz (common in DVDs and Blu-Ray). An ideal rate can be determined using Nyquist’s Sampling Theorem. It is measured in frames per second or Hertz (Hz). What Is a Sampling Rate?Ī sampling rate, sometimes also referred to as a frame rate, is the number of times per second that we measure the amplitude of the signal. Let’s take a look at two fundamental concepts before we jump deeper - sampling rates and types of audio data formats. The large number of audio data file types is due to the number of approaches to compress and package the data. ![]() At a fundamental level, there are not many ways to represent sound. What is audio data? Simply put, audio data is any data format that comes in the form of audio. Summary of the Best Python Tools for Manipulating Audio Data.Changing Audio Data File Formats With Python.Changing Volume of Audio Data With Python.Manipulating Audio Data Sampling Rates With Python.Note that this post is written using Python 3.9 as many audio packages have not yet been upgraded to work with 3.10 or 3.11. You can find a GitHub repo here with all the samples discussed below. This post covers how to do all of that for working with audio data. As Python developers, we’re all familiar with the usual challenges - solving environments, compatibility between versions, and finding the right packages. Python provides us with many packages to manipulate audio data, but they don’t all work.
