Similar to the MP3 audio format, it is specifically designed for audio and supports album art and audio tags, and is suitable for listening, archiving and recording. It is a digital audio file format that offers bit-perfect copies of CDs, but at half the size. Your progress through trials and tracks is shown at the bottom.Īll buttons also have hotkeys.FLAC stands for Free Lossless Audio Codec.
Then enter your choice by pressing the Next button. Once you think you know whether sample X is matches sample A or B, enter your choice by pressing X is A or X is B. You can seek through the tracks using the -5s, << (rewind), and +5s buttons. Once the track is playing, you can switch between the samples by pressing A, B, or X. Start one of the samples by pressing the relevant button: A to start sample A playing, B to start B, and so on. Each trial, X is randomly set to either A or B. A and B are consistent, one lossless and one lossy. In this test, you will be presented with three samples: A, B and X. To reach that bar, you need to do more trials. To compensate for this, the metaphorical bar for determining that you can tell the difference for an individual track (in contrast to telling the difference overall) is set very high - five times higher. When you then test five tracks, the change of that error happening for at least one track is 25% (5% x 5 tracks = 25%). In this case, that means that for each track there would be a 5% chance of thinking you could hear a difference when you in fact couldn't. The statistical cut-off typically used to decide whether something is 'real' - in this case, your ability to tell the difference between lossy and lossless music - is set so there is a 5% likelihood of thinking there is a difference when there isn't. The reason that you need to do more trials to work out which tracks you can tell the difference on is because of the multiple comparisons problem.These files are not cached due to limitations of javascript FLAC audio libraries. You may not want to do it on your mobile.
Note: This test will transfer 30-40Mb of FLAC files.
