It includes many new features such as being able to hide a file's full path. The original author of Spek stopped maintaining it, so I recommend using the fork spek-alternative in all cases.

Spek is an Acoustic Spectrum Analyzer that enables us to verify the quality of any file that contains audio (including videos with audio, such as downloaded YouTube videos). If you have a 320kbps mp3 or other lossy source, it's possible to create a 192kbps mp3 with it, but your version will always be lower quality than a lossless to lossy transcode. To guarantee the maximum possible quality, you should always transcode from a lossless source (such as wav or flac).

Saving a 128kbps audio source as 192kbps increases file size (since there are more kilobytes per second, hence kbps) but does not increase quality.

If you start with a lossy source (such as an mp3), then no matter what you do with it, you'll never be able to achieve higher quality than the original data (such as a flac).

Lossy files are smaller than lossless files since we remove some of the original data (such as frequencies that people may not differentiate) in order to decrease file size.

It's the highest quality you can get it, but at the cost of being large in file size.

Lossless files store the original data.

flac) in all cases, since it will be the same quality as uncompressed lossless (.wav) but smaller in file size.

You want to store compressed lossless (such as.

An audio format can either be uncompressed lossless, compressed lossless, or lossy.

Verify that a 192kbps mp3 is actually 192kbpsīefore we start, let's define a little terminology.

Know when to encode at 128kbps versus 192kbps.

Tell when an mp3 is a 'fake mp3' or when a flac is a 'fake flac'.

Determine the audio quality of any file.

By the end of this guide, you'll be able to: This makes it easier to hear instruments in the song, which helps with both mapping those sounds and playing them in-game.Ībove is an example of an mp3 that was encoded from a lossless source. Since osu! is a rhythm game, it's important that your audio files are the highest quality they can be.
