Analyzing Your Voice with Recordings

Why Analyze Recordings?

When you sing, the voice you hear isn't the same as what others hear. You hear yourself through both bone conduction and air conduction, while everyone else only hears the air-conducted version.

That's why many people think "that doesn't sound like me" when they first hear a recording. Recordings let you hear what others actually hear — and that's the first step toward improvement.

Here's an important principle: use your ears to learn about your voice, not your physical sensations. How singing feels in your body and how it actually sounds are two different things. Often you "feel" like you're singing well, but the recording tells a different story. And sometimes what feels "wrong" actually sounds great. Building a habit of recording and listening back is one of the most reliable ways to improve.

Recording Basics

Equipment

You don't need a professional studio. A smartphone works fine, but keep these in mind:

  • Place your phone 20-30 cm from your mouth — not too close, not too far
  • Avoid echoey spaces (like empty bathrooms)
  • Turn off fans, air conditioning, and other background noise
  • An external microphone helps but isn't required

    • What to Record

  • Scales: Low to high and back, checking pitch accuracy and register transitions
  • Sustained tones: Hold one note for 10-15 seconds, checking stability
  • Song excerpts: The challenging sections of songs you're working on
  • Comparison takes: Sing the same passage different ways and compare

    • What to Listen For

    When reviewing recordings, focus on these areas:

    Pitch

  • Do you tend to sing consistently sharp or flat?
  • Which interval jumps cause pitch problems?
  • Is your pitch stable around the passaggio?

    • Tone Quality

  • Does the sound feel "squeezed"?
  • Is it too breathy or airy?
  • Is the tone consistent between high and low notes?

    • Rhythm and Breath

  • Are you breathing in places you shouldn't?
  • Can you sustain long phrases in one breath?
  • Is your rhythm steady?

    • Diction

  • Are the lyrics clear?
  • Are vowels pure?
  • Are consonants clean and crisp?

    • Using Visualization Tools

    Ears alone aren't always enough — we tend to hear what we expect rather than what's actually there. Visual tools give you objective data.

    Pitch Curve

    The pitch curve is the most intuitive analysis tool. It draws your sung pitches as a line, clearly showing:

  • Which notes were sharp or flat
  • Whether there are pitch jumps around the passaggio
  • Whether vibrato is even and regular
  • Whether slides are smooth

    • Spectrogram

    The spectrogram shows the distribution of all frequency components in your voice. While it looks complex, you can focus on:

  • Whether the harmonic series is complete (good voices have rich harmonics)
  • Whether there's energy concentration in the 2000-4000Hz range (singer's formant)
  • Whether there are unusual noise components

    • Parameter Curves

    Various acoustic parameter curves reveal deeper information:

  • Changes in vocal cord closure
  • Changes in airflow efficiency
  • Changes in compression level

    • How SonaLab Helps

    SonaLab's recording analysis tools let you review with data instead of guesswork:

  • Pitch Recording is the go-to tool. Snap Pitch mode locks to the nearest semitone for quick accuracy checks; True Pitch mode shows the actual curve with vibrato, slides, and subtle deviations. Turn on "Show Note Names" and off-pitch notes turn red
  • Spectrogram Waterfall shows the full frequency picture of a recording — good for big-picture voice quality assessment
  • Symptom Detection auto-flags issues in your recording: extrinsic tension, air leakage, register breaks — so you can jump straight to what needs work
  • Vocal Health Score gives you an overall number to track progress over time

    • The Right Mindset for Analysis

    Don't Be Too Hard on Yourself

    The purpose of recording analysis is to find directions for improvement, not to crush your confidence. Every voice has strengths and weaknesses. Focus on progress, not perfection.

    Compare with Yourself, Not Others

    Compare today's recording with one from a month ago — you'll see progress. Comparing with professional singers will only discourage you, and it's not a fair comparison.

    Focus on One Thing at a Time

    Don't try to fix everything at once. After each analysis, pick the single most important issue as your next practice focus.

    Quick Tips

  • Build a habit of regular recording — at least once a week
  • Save your recordings for future comparison
  • Listen with your ears first, then analyze with tools — this develops your listening judgment
  • Try to relax while recording — tension from "being recorded" affects your natural performance
