I am a keyboardist/pianist. I am having trouble with my keyboard sound at some point.

I usually put my keyboard playing videos on social media. I record my keyboard through a cable to laptop(Audacity), so it won't change 99.9% of sound quality and no noise issues.

The problem is actually problematic. When I use my headphones (High-quality headphones) to hear my recording on any social media I can see no difference between the original and that.

But when the same thing I hear without headphones(with a phone speaker) then my audio sounds so annoying. [I have a Yamaha keyboard and no doubt its sound is at its best]

I have also seen other's recording like Rousseau's: https://www.instagram.com/p/B4K-V-XFD7v/

And this is my recording: https://www.instagram.com/p/CMcHmpiBfhd/

You can literally see the difference. But when you'll check my recording with headphones then it sounds amazing as the original.

So my question is what changes should I have to do before posting my recording.[Bcoz most people are going to see my content without headphones.] Release, Reverb, cut off, and other factors are the main issue on my guess.

  • Not sure what to suggest. The first sounds pretty much like an acoustic piano; the second doesn't. Most Yamahas have a default 'best' piano, invariably the first one you can find, whether it's on a dedicated button [sometimes even helpfully piano-shaped] or just as one of many voices, it's the first one you find.

  • Phones and tablets tend to have tinny sound, lacking bass. Headphones will put back the missing bass and hence sound better. (But don't whack up the bass in Audacity because it will then sound terrible on decent equipment.) The Rousseau recording also sounds better even on modest headphones (and I suspect the third hand helps with fingering).

  • @GrahamNye But why Rousseau's recording sounds good, even without headphones? [Yeah I agree that headphones will help for missing bass sound] Then what is the solution? I somewhere heard interface for recording. Should I buy one for recording? The cable recording is doing the same job. [I see no difference between keyboard sound and recorded sound with headphones. So is it possible that interface will do some job for it?] Apr 7 at 9:43

What changes (in sound terms) should I have to do (in any audio software after recording) to get better sound?

There are no technical problems with your recording that need fixing. I'm afraid I'm the wrong person to ask about using Audacity effects as the only ones I need for my voice recordings are noise reduction and (level) normalization. You can experiment with the available effects or see if another sound design user can help.

I somewhere heard an interface [is better] for recording. Should I buy one for recording?

An external audio interface may be useful with low-level signal sources such as microphones and instrument pickups but is unlikely to offer any advantage with an analogue line-level source such as an electric piano/synth. As you're already using the USB to Host feature for digital recording on your Yamaha PSR-E453 you won't get better than that. People listening via a phone are likely to be listening on headphones or earbuds.

Why [does] Rousseau's recording sounds good ...

I ran your recordings through a spectrogram program on my phone. (Spectroid by Carl Reinke on Android, listening to recordings played through a 2.1 PC speaker system. There is a local 10 kHz signal at -72 dB.)

(I'm an electrical engineer but not a musician.) The voice you're using, which seems to have a musical box quality to my untutored ears, has quite a thin spectral content to it (left hand of the picture) giving a rather thin sound.

The acoustic piano voice used for the Rousseau recording (centre of picture) has a broader spectral content giving a thicker sound. The pink parts of the waterfall pictures represent sound components. There are more of them in the Rousseau recording, giving a richer sound.

For comparison the right hand spectrogram is an instrumental section from the original Queen recording of Bohemian Rhapsody (all instruments).

Artistic decisions are for you, not me. If you want a sound closer to the Rousseau recording you could re-record the piece using an acoustic piano voice rather than the current voice. Or you could choose one of the other 756 available voices. But we don't need all music to sound like a Bohemian Rhapsody cover. You should make your own artistic choices and not worry about sounding like someone else's work.

Having listened to the recordings on a phone, headphones and a 2.1 PC speaker system I can't hear a marked difference between them, beyond the expected lack of bass on the phone. I wonder if you are too close to the subject to get a full view of the difference between the live sound and different playback equipment? Do you have a local musical colleague who can listen to you play live then listen to different playback equipment and give you an independent view of the relative quality of varying playback standards?

(The spectrograms below (upper section) plot log amplitude vertically against log frequency. The yellow trace shows the instantaneous plot (at the end of the recording) while the red trace shows the peak level during the whole recording. The lower waterfall section shows amplitude nominally colour-coded by the scale to the left (in practice pink = sound). The frequency axis is shared with the upper plot. The vertical axis represents about 20 s of time, oldest at the bottom.)

3 spectrograms of instrumentals mentioned in question and Queen original of Rousseau cover.

  • Yes, I do use USB to Host port to record my sound and I agree that the interface won't give me an advantage over it. From your detailed explanation, I understood that I need to make my sound thinker. (Is that right?) Comparing all images I can see that my sound has 278 Hz and others are around 120 Hz. (Is that mean I need to lower my Hz?) Apr 8 at 4:17
  • You mentioned Rousseau has a broader spectral content extending both further down and he has a broader spectral range. (What does that mean?) You also mentioned it has thinker sound filling more spectral. (Does that mean, filling more spectral gives better sound?) And one last question, You said individual notes in the mid-range are also wider (So does that mean, my keyboard is producing thin sound for each individual note?) Apr 8 at 4:23
  • As per your view, what changes (in sound terms) should I have to do (in any audio software after recording) to get better sound? Apr 8 at 4:26
  • Which piano sound are you using on the Yamaha? Usually their prime piano preset is pretty good. The one on your track doesn't sound enough like a real piano.

  • @stackaayush I've reworked my answer to include your comments and omit the technical details you didn't find helpful.
