    S54 engine sound recording with video

    So, I have been on a journey to get some upgrades done on the car, especially a CSL airbox from Karbonius and other bits and pieces.

    I wanted to do before and after comparisons of the engine sound, so started doing some research in online forums and r/LocationSound on Reddit.

    This is my first attempt at recording engine and exhaust sounds, so definitely lots to learn.

    S54 engine sound on SoundCloud

    Would love to hear your feedback and comments on the overall audio quality and how good/bad this engine sounds. There is one thing I noticed where the SM57 provides for a very bassy / roomy sound that can easily overpower the overall recording. This clip is from a half an hour driving session where I played around with levels of all the 3 mics. This one sounded the better of all the various settings.

    If anyone is interested, I can post the full session's recording as well. I have to say, I don't remember which mic was set to what level during the session, but it might be interesting to hear them nonetheless.

    The recording setup included the following:
    1. 2x Shure SM11 lavalier mics
    2. 1x Shure SM57 mic
    3. 1x Zoom F6 recorder

    One of the Shure SM11s is mounted on the oil dipstick and secured to the surrounding area with gaffer's tape. It points to the air box.

    The SM57 points to the engine itself.

    Cables go around the perimeter of the engine bay area and under the wipers. They are all secured in place using 3M masking tape and/or gaffer's tape, depending on the surface.

    Cables go into the cabin by the passenger window sill.

    The exhaust sound is recorded using another SM11 mic.

    Click image for larger version  Name:	IMG_0520.jpg Views:	0 Size:	248.4 KB ID:	161435


    Exhaust mic cable goes through the ski pass through and into the cabin.

    And finally, all the mics feed into the Zoom F6 recorder.

    Very cool, thanks for sharing, very high quality recording, is that clip an uncompressed WAV file?

        Planning on adding a GoPro video recording and posting it to YouTube as well. This was just a starting point to see how the mics work in various positions, etc.

          Any updates on this HanSooloo ? Was looking on fleaBay for some used GoPro's and external mics. Plugged a search in here to see if anyone has been down this road already. Your SoundCloud clip sounds pretty high quality, nice work.

            I will posting clips from my setup soon, now that I have all the equipment and accessories. Can make a thread when I do.

                  This is awesome! Thanks for sharing.

                  Don't have most of my recording equipment anymore, but I still have a 57 somewhere. Might just have to tape it to something in the engine bay to try and accurately record the karb airbox

                    Oh nice! Would you mind posting which mics you used? Rode seems to make quite a few: https://rode.com/en-us/microphones

                    And this is the recorder? https://zoomcorp.com/en/us/handheld-...rders/h4n-pro/

                    Ideally I'd love to get video and audio together. I'm sure that might require editing software (which I don't have). A buddy sent me this video and now I want to get some good video with great audio recorded: https://youtu.be/B4VOThlleaw

                      Sure np, I got the Rode Matched pair condersor mics: https://rode.com/en-us/microphones/studio-condenser/m5

                      Also the recorder was a Zoom h5 not an h4 here is the link: https://www.amazon.com/Zoom-H5-Four-...able-Recorder/

                      Additionally, I got a cheap used go pro 9 off ebay. I am hoping to make some clips this weekend but with the holidays all bets are off.

                      And wow, that clip is amazing! I can only wish to capture something like that...also living where i live the driving roads are no where near as awesome.

                      This is the video i watched to get my inspiration on how to record car audio: https://www.youtube.com/watch?v=XRT44_-Irk8

                        So far, I have been focused on adding a GoPro video recording to properly sync up with the audio recording. This has been more troublesome than I had anticipated, because of GoPro's firmware issues in being able to handle externally fed timecode information.

                        Main issue being, the ZOOM F6 sends timecode info on the RIGHT audio channel, and the GoPro expects it on the LEFT channel. So, I ended up getting a few cables to reverse the audio channels (RED RCA to WHITE RCA and vice versa using the below cables):
                        1. 3.5 mm to RCA breakout cable: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
                        2. RCA to 3.5 mm cable: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
                        With the audio channels swapped, the video recording from the GoPro seems to have the correct timecode info on the MP4 file it generates and can be properly synced in an editing app like DaVinci Resolve (free version).

                        Having found a way to get timecode to work, and hence the sync between audio and video, I am now trying work through video stabilization issues: with the GoPro mounted on a headrest mount, (1) if I use GoPro's own image stabilization features, the video has this annoying left/right panning effect as the GoPro's firmware tries to compensate. (2) if I turn the image stabilization OFF, then the vibration is too much for anyone's stomach to handle

                        I will post more updates as I try different things. Would love to hear how others are addressing similar issues.

                          I know very little about audio engineering and don't want to spend a million hours dealing with some programs to sync up and then editing, etc etc, so I went with the KISS method and duct taped a mic inside the engine bay. I dismantled an old suction cup cell phone mount and hold it in my mouth for video, set the mic and camera to record, then just honk 3 times to sync up the audio between mic and camera later in iMovie on my ipad. The first time I tried this I just used an old cell phone as the mic and stuck that next to the intake and it worked great. lol.

                          Driving starts at about 5 min

                          This is more of an E46 M3 appreciation video than anything. Love this car.If you want to see more of me or the cars you can always hmu on IG @ JT_E30DISCLAIM...

                            After many additional attempts, I was able to get an audio + video recording here:


                            In addition to the 3 mic's, now I have 2 GoPro's: one looking ahead, and the other looking at the dash. Compositing them for the YouTube recording later. I am not very happy with the stabilization that GoPro does, so planning on learning a bit more about what DaVinci Resolve can do with its Tracking feature.
