Arto Koivisto<p>Car audio nerding tangential to previous toots: The rotational value in Hz of a combustion engine ofc corresponds to audible harmonic series. These are well visible in visual metering like spectrograms.</p><p>The harmonic series follow cylinder count. So a 4-cylinder car often has the strongest harmonic sitting at multiples of 4, etc. This same car idling at 7 Hz, could have strongest harmonic between 8-16* (56-112 Hz), depending on the exhaust pipe config.</p><p><a href="https://mastodon.gamedev.place/tags/GameAudio" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>GameAudio</span></a> <a href="https://mastodon.gamedev.place/tags/Cars" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Cars</span></a> <a href="https://mastodon.gamedev.place/tags/SoundDesign" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SoundDesign</span></a></p>
