The samples below consist of two tracks. The top one is the original mix and the bottom one is the finished master. Both tracks have been normalised for fair comparison. The actual difference in loundess between the mix and the master may be much more pronounced. Recently we decided to make testing samples more enjoyable, so we made a video with audio samples. To properly compare samples, please set video resolution to 1080p and wait until file is fully buferred. To make it easier to navigate I created video playlist with all Audio Samples.
The samples below contain the original mix and the finished master in one audio file. Please note that the mixes have been normalised (up to .3dB FS) for fair comparison.
