Audio compression is a time consuming process. Whether you are a professional DJ, a musician or a music lover, storage space will always be an issue. The audio compressor plays an important role here, reducing the size of files so that they find a place to rest on your PC or devices. Audio compression software is also necessary if your music file format is not supported by your portable player or other devices. You will also need to compress audio files if you want to transfer MP3 files or upload them to social networks or other websites. This article explains the different types of compressors and their features, including online audio compressors, the best free audio compression tools for Windows or Mac.
Here are several simple and effective ways to reduce large audio files to a manageable size.
Compressing Audio Files with iTunes
- Once you have chosen a type of audio file, you can easily convert the file using iTunes.
- In the iTunes drop-down menu, click Preferences and navigate down to the Import Settings option. A new window will appear, where you can change the way files are imported by selecting another option from the Import with drop-down menu.
- For most people, it is best to use an MP3 format. If you wish, you can set the quality a little lower to save extra space by clicking Settings > Customize.
- Then right-click the file you want to compress and select Create MP3 version. Apple iTunes will then compress the audio file according to the quality settings you choose and place the new file directly into your iTunes music.
Compressing an audio file with Audacity
File compression sometimes requires converting a file from one format to another. This usually happens when you switch from a lossless format to a lossy format, such as WAV to MP3. The conversion process will reduce quality, but the application you use to convert will also affect the sound quality. We therefore recommend using Audacity to compress an audio file.
Download and install Audacity. Open the application and drag the audio file you want to compress onto the application window to open it. Once you have added it, go to File>Export. Select a lossy format, for example to export it to MP3.
Once you have selected the format, you need to choose the bit rate of the audio file. The bit rate of audio files is the same as that of a video file. The higher the bit rate, the larger the audio file will be. You can choose a lower bit rate, but simply converting a file from a lossless to a lossy format will reduce its size. You can try both and see which format you prefer.
Change the bitrate mode to variable or constant and save the file.
We started with a WAV file size of 2.46 MB. When it was converted to a lower bit rate MP3 file, the size was 230 KB, which is a pretty big difference.
So now you know how to compress MP3 and other audio files. All of the tools listed above will do the trick, and they are generally easy to use.
Audio compression is essential if you record it yourself, otherwise you will end up with huge files that are too large to share or convenient to use. But that’s only part of the process. Check out our tips to help you make better audio recordings so your recordings sound even more professional.
