If you find this useful and/or have any comments or suggestions then do let me know via the comment section below (please read our website rules before posting). Note that the file size reported by your device may vary slightly from that shown due to file allocation methods, possible differences in the amount of header information and/or the fact that some operating systems calculate hard disk space differently from others (e.g., some calculate it in binary and call 1kB 1024 bytes whilst others – and most hard drive manufacturers – calculate it in decimal and call 1kB 1000 bytes) – this calculator handles both methods. For compressed files encoded with VBR (Variable Bit Rate), the displayed file size can be slightly less accurate because in this case the bit rate can vary depending on the programme material. For compressed files encoded with CBR (Constant Bit Rate), the displayed file size should be as accurate as possible (notwithstanding variables such as header information etc- see below). requires only the Bit Rate information (in this case the Sample Rate, Bit Depth and Channel information is ignored). In addition to the duration, calculating the size of compressed files such as MP3 etc. Calculating the size of uncompressed files also requires the Sample Rate, Bit Depth and Channel information (but not the Bit Rate, which is automatically calculated).

Moving the mouse over the plot window will reposition the green cursor showing the trade-offs that can be made between the two selected parameters and the remaining parameters values. The 'Plot X vs Y' command (Alt + Y) displays the following graph. The amplitude of each component is given in LSBrms.

The noise and distortion components are plotted as a percentage their contributions to total noise when summed in RSS fashion. The pie graph command (Alt + G) displays a pie chart showing the contribution of each noise source in the data convertor or signal chain. It appears following an entry or import command. 'Inconsistent' indicates that all parameters may not be consistent. It appears following a Find (Alt + F) command.
