Shortly after our October online piano party, one student asked, “Bruh, how come you sounded so clear when the rest of us sounded just okay?”
To which, I replied: “It’s because I didn’t use the device mic.”
“You should write about that. How to improve your sound.”
So here I am.
Simple Sound Hacks
Many students and teachers use phones and tablets for online lessons and recording. Technology has come a long way, but I’m sure you have noticed that Zoom and some of the other video conferencing platforms fail to capture the subtle nuances in upper intermediate and advanced repertoire. Choosing “Enable Original Sound” and “High-fidelity Music Mode” only goes so far.
One simple microphone hack you can experiment with is the microphone’s distance from the piano. I’m no physicist or sound engineer, but I have worked enough symphony and jazz concerts at Arts Commons to take note of where the audience and microphones are positioned in relation to the stage. I have used that as my starting point to experiment with.
If you or your student are hearing a lot of sound distortion, chances are, the microphones are too close to the instrument. My students and I have learned that depending upon the piece, the sweet spot for the microphone in a phone, tablet or laptop is anywhere between two to four feet away from the piano and approximately at someone’s ear height when sitting.
The louder the piece, the farther the microphone needs to be. Alternatively, I adjust my students’ microphone volume when we’re livestreaming.
The louder the piece, the farther away the laptop is.
Using earbuds or headphones will help reduce audio echoes when in Zoom, StreamYard, Discord or any online platform. You may need to get a stereo audio extension cable now that your device is farther away. They retail for less than $10.
If a student insists on positioning their device at the edge of the keyboard, you are going to hear a significant amount of sound distortion. One easy hack is to have them place an eraser or something rubbery like a hockey puck beneath their phone or tablet. One of my university professors placed her upright piano on four hockey pucks to dampen the sound transfer from her townhouse unit to her neighbour’s unit below. It worked extremely well.
If there are lot of hard surfaces in your studio or your students’ practice areas, you can experiment with sound baffling to help minimize reverberation. Although there are sound baffle panels and blankets out there, you can easily achieve results by adding more soft materials to the room, such as pillows, blankets and towels, which will absorb the sound.
Levelling Up Your Sound
One thing I learned from livestreaming and producing content for my YouTube Channels is that if you really want better sound, you need to invest in better microphones designed for high-fidelity sound.
I started by using my Zoom H2N surround sound recorder (approx. $230) as a USB microphone, connected to my computer. It has five built-in microphones and four recording modes. You can get recording studio quality with it. There are several newer models that come with many bells and whistles. Perhaps too many, so do check the specifications to see what best fits your needs and your computer’s specifications.
There are five microphones that consistently pop up in “best microphones for music podcasting” searches that are worth checking out. They are the Blue Yeti ($125 and up), the Rode NT USB ($219), the Rode Procaster ($300 and up), the Audio-Technica AT2020USB+ ($219 and up), and Shure MV7 ($229 and up).
The second thing I learned is that if you are doing any piano combo work, be it piano and voice or piano and guitar, each instrument needs its own dedicated microphone. Otherwise, the piano will just drown out everyone else.
The only exception is when I fiddle with the microphone settings. When I teach online, I sometimes use my Razer Blackhawk Gaming Headset (approximately $100). The microphone is on the headset, so my voice is louder than the piano. When using the H2N unit, I adjust the recording mode to 90 degrees X/Y stereo and zero gain (no signal amplification) and position the microphone in front of me (and then just plug in earbuds into my stereo. These adjustments allow the microphone to catch more of my voice than the piano.
If you decide to take the plunge and buy one of these microphones, hop onto YouTube to get more tips and tricks. Check out Bea Chu, Todd Audio, and Christian Henson Music on YouTube.
Earlier this year, I invested in a stereo pair of Lewitt LCT 140 Air:
I was planning on doing an unboxing and review video. This screenshot is from the unboxing. I pretty much started using them as soon as I plugged them in. Hopefully, I’ll get around to completing the unboxing/review, but in the meantime, you can hear what they sound like in these two videos:
Recorded with Sound set to Flat, Filter OFF and Pad set to O. No additional sound FX.
Recorded with same microphone settings, with the addition of Small Stage FX setting on the Mackie.
These days, I use my Shure PG4 Wireless Headset System, AT4040 Condenser Microphone and Sennheiser HD 280 Pro Headphones plugged into a Mackie ProFXv3 Mixer Board for content creation and livestreaming. When recording piano only, then I break out the Lewitts That way, I can really adjust the sound for multiple instruments and add sound effects to make it sound like I’m inside a concert hall or recording studio.
