following question: is it possible to replace for an example the system sounds of an electric device when turned on, like the peep of a oven or so, or when you lock the car etc. If yes, how complicated is that or in other words how can it be done? Thank you for your help, best, christoph

    completely depends on how the device is made! it may be hardware wired (changing components, if even accessible), or software driven (changing firmware)... – B. Go Feb 20 '20 at 17:19
  • thank you for replying! if it is software driven, can´t you basically replace the soundfile with another one (same file name, formats etc) or is that to naive thought? – christoph stock Feb 20 '20 at 20:03
  • you would need access to the full firmware, some of the build tools (may be compressed, with checksum...), and the hardware tools to flash that (not always just an usb port, but a full "probe" to connect... So not likely doable for products you didn't design yourself! Much easier to remove the sound (find the speaker and cut its wire/trace, if visible, which actually may not be the case either). Changing components would likely just change the frequency of the beep. And there are often 2 summed. – B. Go Feb 20 '20 at 22:39
  • Some chips also do sounds like the 8 kind of car alarms also available as keychains. They are one time "flashed" and can't do anything else than their 8 sounds. HK628 according to https://ask.metafilter.com/111689/Where-did-the-multisiren-car-alarm-come-from – B. Go Feb 20 '20 at 22:39
