    Audio file compression

    Is there any way to compress audio in UE4? I've just gotten around to adding a music track to the level I'm working on, and I don't see any options except for .wav. While I would very much like to use music and feel that it adds a lot to the level, the .wav is a whopping 20mb for 120s of playback. This wouldn't be an issue in a retail game, but when people are probably going to have to download the level from a redirect, that's way too much- custom assets mean the map is already getting large as is. Am I just missing a way to compress this? Even FLAC would be smaller, but OGG or MP3 would be preferable.

    When you publish your level to share to the public it will be compressed automatically for you!

    Keep on Mapping!

        sorry for my late answer, but focuses on sharing, first let's take a look at the basic information in these formats. FLAC: Developed by the Xiph.Org Foundation, the Free Lossless Audio Codec (FLAC) has much appeal due to its royalty-free licencing and open format. FLAC is both a compressed and lossless audio format, with file quality able to reach up to 32-bit / 96 kHz (by comparison, a CD is 16-bit / 44.1 kHz). FLAC enjoys the advantage of a reduced file size (about 30 to 40 percent smaller than the original data) without having to sacrifice audio quality, which makes it an ideal medium for digital archiving (i.e. using it as the master copy in order to create compressed/lossy files general listening). WAV: Also developed by Microsoft, the Waveform Audio File Format (WAVE, or more commonly known as WAV) is a standard for Windows-based systems and compatible with a variety of software applications. WAV is both an uncompressed (but can also be coded as compressed) and lossless audio format, essentially an exact copy of the source data. Individual files can take up a significant amount of space, making the format more ideal for archiving and/or audio editing. WAV audio files are similar to PCM and AIFF audio files. MP3: Designed by the Moving Pictures Experts Group (MPEG), an organization that develops standards for coded audio and video programs, the MPEG-1/MPEG-2 Layer 3 (MP3) is arguably the most prolific and supported audio file type. MP3 is both a compressed and lossy audio format, with bit rates ranging from 8 kbit/s up to a maximum of 320 kbit/s, and sampling frequencies ranging from 16 kHz to a maximum of 48 kHz. The smaller file sizes of MP3s means faster file transferring and less space used, but at the cost of a reduction in sound quality (versus lossless). more info: https://www.lifewire.com/different-t...-files-3134920 then you should know that WAV is the best audio format to compress http://www.videoconverterfactory.com...-wav-file.html
