Hi guys! Welcome to the exciting world of EUC AVAS!!! This thread has been created to make the most of the very cool AVAS function implemented by @Seba in EUC World's latest release. While the main (official ) purpose of AVAS is to emit sounds to alert passersby of our presence, this thread wouldn't exist if our inner child weren't ecstatic about the possibility of making our wheels sound like race bikes, spaceships and jet planes... The creative possibilities are endless and some users have already begun experimenting with custom sounds, so the time has arrived to create a dedicated thread where you can find cool sound packs created by others, upload your own, share and suggest ideas, etc. First of all, a description of the basic sounds that make up AVAS, what they are, how to use them and considerations to bear in mind when creating sounds for AVAS: Engine start: This sound is played when you connect to the wheel / enable AVAS, so it should be an engine starting (whether internal combustion or a spaceship powering on). A second of idling after start-up could be a nice touch (it's worth testing before you load it to EUC World to make sure that the end of this sound matches well with the beginning of the engine idling sound the follows it) Idling: This sound is audible when you are stationary, so it can be anything from a car/motorcycle/truck engine idling sound to a helicopter or a UFO hovering. It will be played in a loop when stationary, so regardless of file length, it's important for the end and beginning to match well so the transition is seamless. This can be tested before uploading to your wheel by opening it in your favorite audio player and playing it in a loop. The same applies to all sounds that are played in a loop. Speed-dependent sound: Sound whose pitch varies according to your speed, creating a realistic effect where your engine sound matches your riding (when accelerating or decelerating, going faster or slower, etc.). Since this sound's pitch will be altered by EUC World to match your speed, it's important for it to be a flat, sustained sound: for IC engine sounds, think of sustained cruising sounds with no acceleration/gear-changing/deceleration (this can be trickier to find than you might think). It will also be played in a loop while you're riding, so a seamless transition is important. Current-dependent sound: Think of it as a turbo-charger that kicks in when you accelerate (this does not replace the speed-dependent sound, it plays on top of it). The included sound is a high-pitched whistle, but the possibilities are endless, from a NOS effect to a jet propulsion thrust to wherever your imagination takes you. I've experimented with flat sounds so far, but I'm sure there are tons of others possibilities (heavy revving, for instance?) Temperature-dependent sound: This sound can be seen as a fun alternative to temperature alarms that alert you in an entertaining way that your wheel is gradually creeping towards overheating. An excellent use-case suggested by @Seba would be for @Marty Backe's Overheat Hill™ tests: steam escaping from a boiler (steam-train style), just subtly present as the wheel reaches a warm operating temp. (50ºC, for instance) and which gradually increases in volume until you reach 60ºC (or whatever max. temp. you've set). Aside from being a fun alternative (tons of sounds come into mind: engine rattling, hissing, etc), it provides real-time temperature feedback on warm days/steep climbs, gradually increasing its presence, as opposed to a static temp. alarm, that doesn't activate until you reach the max. value you've set for the alarm. Engine off sound: Self-explanatory. Might require some fiddling to play nicely with the idling sound the precedes it. You can find a quick guide on how to install user-created AVAS packs here: Sound specifications for users thinking of creating their own packs: Most common file formats are supported (WAV, mp3, AAC, ALAC, FLAC---correct me if I'm wrong, @Seba), but it's preferable to use sounds that are uncompressed (WAV). Update: For idling, speed-dependent, current-dependent and temperature-dependent sounds it's best to use 16-bit, 32 kHz mono PCM WAV format and keep them less than 1 MB of size. This is proven to work on most Android devices. Upload suggestions/requirements (IMPORTANT!): Since this site has a limited hosting capacity and is supported by one person only, please do not upload sounds directly using the forum attachment function. We're studying the possibility of having a dedicated AVAS sound-hosting site, but for now, I think the best solution is to share download links from Dropbox/Google Drive/whatever cloud service you use. Ideally, sounds should be named so they are easily identifiable (spaceship_start.wav, spaceship_idle.wav, spaceship_speed-dependent.wav, etc.). To keep things as organized and user-friendly as possible and not have a bunch of different files scattered throughout the thread (imagine having UFO startup one page 1 of the thread and UFO speed-dependent on page 4...) our current approach would be to bundle sounds together in a zip file and upload them as sound packs. @Seba is studying the possibility of creating a sound-pack download and auto-install function at some point, which might require a specific file-naming scheme and upload route, but this feature is still on the drawing board and he's just finished an intense development stage (AVAS, Tizen Support, etc.), so I reckon he deserves a break and downloading and loading sounds packs into EUC.W manually is no big deal for users considering the amount of development time that has gone into making AVAS possible. Now it's users' time to shine, put your lockdown idle-time to good use and unleash your creativity! Pro tips: - Your phone needs to be connected to your wheel's Bluetooth audio service (like when you play music through it) for AVAS to be played through your wheel's speakers. Otherwise the sound will come from your phone. If your wheel doesn't have in-built speakers, you can easily use a portable Bluetooth speaker (I'm sure @Unventor will be happy to share his setup) - When selecting new sounds in EUC.W., you need to disable and re-enable AVAS for changes to take effect - AVAS can be enabled/disabled by assigning it to a quick gesture on your Flic button, smartwatch, tapping on the gauge on the app's main screen, etc. - Sounds can be downloaded from a numbers of free sources (Youtube, freesound, zapsplat, freesfx, etc.) and edited using the free, open-source and cross-platform Audacity audio editor, or Adobe Audition if you're using Adobe products. There are plenty if tutorials online, but who knows, maybe there'll be an AVAS-specific tutorial by someone in the EUC World Team in the not-so-distant future... - Getting sounds just right: With IC engines, a 1/4 second more or less at the beginning or end up an idling or speed-dependent sound can mean the difference between matching engine strokes and seamless playback vs. an out-of-whack AVAS. Play around until with them you get them to your liking before loading them into EUC World for real-world testing. - On that note, I've found that the best way to test sounds prior to loading them into EUC.W. is to add them to a playlist using your favorite music player and play them in order: engine on, idle, speed-dependent sound, idle, engine off and see if they play (more or less) seamlessly. I'd say that pretty much covers the basics. I'll update/edit this introductory post with any significant/relevant changes. Edit: This thread isn't exclusively for sound-file uploads: Youtube videos with real-world examples of your crazy wheel sounds are also welcome here! (whether you're riding around the neighborhood or trolleying your wheel down the hall) One last note: A lot of people expect to find a changed world when COVID-19 restrictions are lifted and they can finally resume their life. Little do they know exactly how different a world they're going to encounter, full of lunatics from the future riding one-wheeled Harleys, spaceships, UFOs, helicopters, jet fighters, Millennium Falcons, Jetsons cars, etc.
