Android devices, Apple Music and Youtube tend to use this format. Short for Advanced Audio Coding, the AAC format is similar to the popular MP3 and is generally better for streaming over mobile devices. ![]() Here’s a closer look at each audio file format: The exact format you choose will depend on what your needs are and what tradeoffs you’re willing to make. File types include MP3, AAC, and Ogg Vorbis (OGG) Some quality may be lost, or degraded, but the files tend to be smaller. Once the audio is compressed, it won’t decompress back to the original size. Data will be lost in the transmission with lossy audio formats. File types include M4A, MQA, WMA, FLAC and ALAC. They’re usually much larger compared to lossy formats. These files will ensure the sound quality is intact because it decompresses files back to their original size. Compressed audio is broken down into two different formats. Compressed audio means that portions of data are taken out of the recording to make it smaller and easier to store or share. Uncompressed audio, which includes WAV, AIFF, and DSD file types, means the data remains the same size from the transmission to the receiving end. uncompressed: Understanding audio file formatsĮach audio format is either compressed or uncompressed. You want to have your audience be able to access your audio fairly easily while balancing the quality of the sound. Understanding who your listeners are and where they will listen is important when choosing the right file format. The higher the bit depth, the fuller or louder the sound will be. The bit depth is the number of bits per sample. ![]() The latter is the number of samples-sound, or the signal amplitude-per second. Other factors when it comes to audio formats include bit depth and sample rate. It can come at the cost of more data lost in compression, affecting the sound quality. Typically, the lower the bitrate, the smaller the audio file. ![]() The speed of audio codecs is measured in bitrate (kbps), or thousands of bits processed per second-this number can vary even within the same audio format. Programs used to process audio files are called audio codecs which compress audio for transmitting data and decompress it when the data is received. Audio file formats are different forms of compression, all differing in quality the listener will experience on the receiving end.
