Audio compression is the process of compressing audio files to make audio size smaller, which can help users save more space in smartphone, computer or other storage devices.

As we all know, there are different factors that are related to the size of an audio file. And how to compress audio according to these factors may annoys you. To help you get away from the agony, here we will show you several free ways to compress audio on Mac and Windows.

Factors related to audio file size

Before we start shrinking audio files, we need to learn these factors related to audio file size, which will help us to find a quick way when shrinking audio file size with an audio compression tool. There are different factors that are related to audio file size, including:

Codec: It is the way that an audio file is compressed. This determines how small the size of the audio file is.

Bit rate: It is the quality of an audio file. Higher bit rate means better quality. However, this also means a bigger size. So if you want to compress audio file, one way is to lower the bit rate.

Channel: This factor determines how audio travels from the source to the destination. For instance, a stereo source has two channels, while a mono source only has one channel.

Sample rate: This refers to the number of samples of audios carried every second. Lower sample rate decreases size. For example, 22.05 kHz is popularly used for mp3 files.

Step-by-step Guide to Compress Audio Files with Pavtube Video Converter Ultimate

Step 1: Add audio files to the audio compressor

Click 'File'>'Add Video/Audio' to add the audio files that you want to compress.

Step 2: Choose different compression methods

Method 1: Choose a codec with higher audio compression ratio. This method is very effective, but will decrease audio quality apparently. In most case, MP3 is a audio format that stores compressed audio data with good quality and small file size. Plus, with same audio quality, AAC file size is smaller than MP3. Just go to 'Format' bar>'Common Audio' to choose 'MP3 - MPEG Layer 3 Adio (*.mp3), or 'AAC-Advanced Audio Coding(*.aac)'.

Method 2: If you don't want to change video format, you can change the audio settings by clicking 'Setting'. Generally, the lower bit rate will cause the smaller audio size. Take MP3 as an example, an MP3 file with 128kbps bit rate can save nearly 1 MB to 5MB song without any decrease in quality when downscale the audio bit rate to around 90 kbps.

Step 3. Start to compress audio files

Hit the right-bottom 'Convert' button to start audio compression process. You'll get the compressed audio after a while.

Besides Pavtube Video Converter Ultimate, there are many other free audio compression tools we can easily download from Internet. Although they are less functional than Pavtube, but these tools can also help you compress audio file smoothly.

Free Audio Compressor For Mac

The exclusive 'Overall Audio Quality' option on our website is inspired by 'JPEG Quality' option in image compression. It's more intuitive than setting audio parameters such as audio bitrate or sample rate etc. A few formats are lossless audio formats, for example, WAV (Waveform Audio File Format) is typically uncompressed audio used by audio experts for maximum audio quality. We created new calculator to calculate 'Overall Audio Quality' value for these uncompressed audio files. Compression algorithm for lossless audio formats is different from compression algorithm for lossy audio formats such as MP3 or OGG etc.
