We’ve compiled the following list of audio compression tools to help you find an option that best fits your needs. Whether you want to achieve basic file compression or also do some editing, one of the free or premium software solutions on this list should help you out.
Free Audio Compression Software
Online Audio Converter is a website that is free to use for audio file compression. You upload the file you want to compress and can make changes to its quality to reduce file size, including advanced settings like sample rate and mono or stereo output. You can also choose what file type you want the compressed version to arrive in. One click makes it easy to download the new, smaller file. A few hours later, the app’s developers delete your file from their servers. This is a great solution for those who want free service and don’t mind exposure to the cloud.
The team at Monkey’s Audio have developed a program to compress the size of a file without compromising playback quality. They promise a bit-by-bit compression of your file that reduces its size without removing the nuances of the recording. The program interfaces well with common Windows software like Media Player, and you can always decompress your files if you need the original version back.
Audacity is a software application for both recording and editing multiple audio tracks. You can even use it to record audio that is being streamed, such as a webinar. Once you’ve recorded, you can edit or clip the sound file to isolate only the parts you want. Audacity achieves compression of audio files through volume compression, which you can watch in action in this YouTube tutorial. Before you export the compressed version, you’ll be able to listen to the recording and make the volume louder or quieter as necessary to achieve perfect sound and reduce your file size at the same time.
Paid Audio Compression Software
There is a free version of WinZip that can be downloaded for Windows, Mac, or Android, but the paid version of the software could be worth the investment. WinZip is a file compressor that can make any type of file smaller, not just audio files. If you’re working with MP3s, WinZip makes them smaller by 15-20% with no compromise in quality, thanks to their .zipx format. This improved quality is essential when you’re considering transcription of a file.
One of the main benefits of Advanced Audio Compressor is batch compression. If you have multiple audio files, you can upload them all into the software and make any changes before compressing them at once into a shareable folder. The program allows you to see, in real time, just how much the size of your sound file will be reduced. There’s also a good amount of mobile functionality for those who need to compress files on the go. Winsoftmagic, this program’s developer, offers a free trial download to experiment with the interface. However, to actually save and use audio files, you’ll have to purchase the software.
If you need to keep your audio files secure and organized, Ashampoo Zip Pro is the solution for you. This software boasts full encryption, and allows you to create online drives to share with team members as needed. It also integrates with Google Drive, Dropbox, and other cloud storage leaders to make backing up files easy. There are advanced compression file type options available in this software so if you need to go beyond .zip or .zipx, this solution has you covered.
Clearly there are several options available to help with audio file compression so it’s important to do research and make sure you’re using a tool that preserves the integrity of your file and respects your security and privacy.
