 The startup (and attach) chimes are located in the UEFI firmware. To extract it, use [https://github.com/LongSoft/UEFITool UEFITool]. Then, search for the BootChimeAudio section. Finally, extract the Raw Section inside it by right clicking on it, and selecting <code>Extract body...</code>. Since it is a CoreAudio file, make sure to add the .caf extension on the file. The similar method applies to the attach chimes, but the section has no codename on it. To easily look for the chimes, after opening the UEFI firmware in UEFITool, select <code>Action</code> -> <code>Search...</code>. From here select <code>Text</code> and search for <code>caff</code>. Make sure to disable the Unicode option. <br> On T2 Macs, the UEFI Firmware contains the older 1998 chime.
 The chimes are CoreAudio (CAF) files with the following attributes: 16-bit, Mono at 44100 Hz with the IMA QT ADPCM Audio (ima4) codec.
