Compress Large Audio Files by Audio Size Reducer

You know what, device storage space often comes at a premium contemporarily. As you hanker for reducing large video file size, in the face of high-res lossless digital music, you'll sigh for insufficient storage on your devices. Compared to those DJs, audiophiles, musicians, general listeners won't be able to tell much difference between lossless and lossy audio without specialized high-quality speakers or headphones. So they also have a strong demand for audio compression since smaller files mean less memory used on the device.

Two Cases to Make Audio File Smaller

There are several ways to compress an audio file. But everything depends on the source file quality. If you have purchased or downloaded lossless audio files close to CD audio like WAV, FLAC, ALAC, etc, you can always convert them to a lossy audio format such as MP3, WMA, AAC, etc. to fix “how to reduce audio file size” issue and keep the satisfied quality greatly. But there’s one thing you need to know: converting lossless audio to a lossy format is pretty easy while converting lossy audio back into higher-quality lossless formats is not possible now because this will only result in a larger file size with a worse sound quality.

Another case is when you have audio files in a lossy format, making them even smaller is still feasible. The most direct and effective way is to lower audio bitrate. You know, bitrate is the most crucial parameter to determine the size and quality for both audio and video. The higher the bitrate, the larger the file, also the better the quality. Take MP3 as the example, you can compress MP3 file size by changing MP3 bitrate, but better not go lower than 128 kbps. Really sucks! Besides, it also works when you cut audio, change sample rate and bit depth of audio file as well as remove metadata.
