3. Compress WAV files

There are three methods to help users to make WAV files smaller than before.

Option 1. Changing another format to reduce WAV file Size

Find the button “Convert all files to” to continue the next step. You choose another format, such as MP3, M4R, or others. Take MP3 for example. Under the sub-tab of MP3, you can also choose among high-quality, medium-quality, and low-quality. The file size will decrease with the change of quality. You can select any one based on your needs. The MP3 format with 128kbps is almost the same quality as the WAV(to some degree, the nuance is imperceptible for human ears). Therefore, you can find the button “create custom” on the lower of the MP3 sub-tab to change the bit rate or choose directly the “low-quality” item. After finishing the compress, you will see the converted audio file size decrease dramatically.

You should select a proper format that suits your need. Some musicians and experts are fond of WAV, AIFF and APE, while most users are inclined to choose audio formats like MP3, CAF, or M4R.

Here are the options you have: all the output audio formats: AAC, AC3, OGG, M4A, CAF, MP3, M4R (audio formats with quality loss in different degrees), and AIFF, APE, WAV, FLAC (audio formats without quality loss).

Option 2. Decreasing the bitrate  to make the WAV file smaller

Here you can still choose the WAV format and just change the parameter of the bit rate. In fact, for the most part, people nearly cannot find the difference between 128kbps and higher bit rates (even using very professional speakers to play such audio). But you should know that the bit rate cannot decrease to below 128kbps, otherwise, the audio quality will be worse for listening. Using this way also can reduce WAV file size. You just need to find the button “Create custom” on the lower of the WAV sub-option to change the bit rate. After finishing the compress, you will see the converted audio file size decrease dramatically. In brief, the higher the bit rate, the better the audio quality, but the larger the encoded file.

After changing the parameter, you find the tap “Output” on the lower left, then select a file location to save the converted WAV audio files. Lastly, click the button “Convert All” to compress WAV files.

Option 3. Changing format and parameters simultaneously to shrink WAV file

Such a way to compress WAV file size means that you can change both the format and the bit rate simultaneously to make WAV files smaller. In other words, you can choose other formats like MP3 or M4R and adjust the parameters like 128kbps or a higher bit rate to compress WAV files.

About WAV

Waveform Audio File Format (WAVE or WAV) is one of the audio file formats standards. This file not only can record all kinds of mono or stereo sound information but also can guarantee sound qualification. However, the WAV file has a fatal drawback: it takes up too much disk space (about 12 megabytes per minute of music) on users’ PCs. In light of the large storage space, emailing, storing, and sharing WAV files become so inconvenient. Therefore, users should know some ways to compress WAV files. If you want to compress WAV files quickly and easily without any disturbing advertisements and insecure links, you can try Aiseesoft Video Converter Ultimate by following the aforementioned steps.

Compress Wav File Online

You can also use online programs to compress WAV files, such as Online UniConverter or Online Audio Converter. However, although you can use it without installation, the disadvantages are so obvious. For example, the conversion speed is based on the network connection, compressed WAV file does need to be under 100 MB or limited formats. Therefore, maybe this video converter can lead to a better experience than some online compressors.

Why Wav Online Compressors Are Inefficient?

There are many online tools claim that can help to compress files for you. However, not all of them work. You need to upload the file and test them one by one. Not to mention the time you waste on uploading and downloading the output file. Even worse, sometimes you may negligently click on the scam ad from the “free” online tool site and lost money.
