Salvageable vs Clipped Spectral Diagnosis
Inspect waveforms and Spectral Frequency Displays before touching plugins so you identify steady hum, broadband hiss, room decay, transient clicks, or digital clipping accurately.

Dialogue Audio Repair: De-Reverb, Spectral Cleanup & Wind Rescue
Rescue echoey room dialogue, outdoor wind rumble, HVAC hum, and lavalier rustle using spectral diagnosis and staged processing without robotic underwater artifacts.
Every filmmaker and editor eventually inherits compromised location audio: a wireless transmitter drops out leaving only a hollow camera mic, glass condo walls ring around every syllable, or outdoor wind slams a lavalier capsule. Cranking one-knob cloud AI cleanup to 100% smears Persian and accented English consonants into watery synthetic lisps. In this course, we read waveforms and spectral displays first, separate de-noise, de-reverb, wind/plosive filtering, and mouth de-click into clean stages, and blend parallel dry/wet tracks for authentic human tone.

Course Learning Pillars
Core Capabilities Developed in This Course
Every learner starts from a different background. These are the core capabilities this course develops, paced to your goals across the sessions we plan together.
Staged De-Noise, De-Reverb & Resonance Cuts
Process broadband noise and hollow room reflections in the right sequence, pairing moderate de-reverb with surgical 250–450 Hz room-boom EQ cuts.
Wind, Plosive & Mouth-Click Attenuation
Tame sub-120 Hz wind buffeting and P/B mic pops without thinning chest warmth, and lasso-attenuate clothing rustles, coughs, and mouth clicks mid-sentence.
Parallel Dry/Wet Blending & Room Tone
Blend cleaned voice stems against EQ-shaped original audio and lay continuous room tone underneath so speech never sounds gated, synthetic, or underwater.
Course Syllabus
Core Concepts & Topics Covered
Below are the main concepts and topics covered in this course. In your Free Online Intro Session, we align the exact depth and number of sessions to your experience and goals.
Topic 01
Waveform & Spectral Diagnosis Before Processing
Reading visual frequency maps in Adobe Audition, DaVinci Fairlight, or iZotope RX so every filter addresses the real acoustic problem instead of guessing.
- Distinguishing horizontal harmonic hum lines, vertical transient clicks, and smeared room-reverb tails on a spectrogram
- Evaluating flat-topped 24-bit digital clipping vs recoverable 32-bit float peaks and mild analog saturation
- Sweeping a narrow EQ bell to locate ugly condo room resonances and air-conditioner fundamentals
Topic 02
Steady Noise Reduction & Echoey Room De-Reverb
Combining spectral noise prints and modern neural dialogue separators in moderate passes so background noise drops away without phasey chirping.
- Capturing clean noise prints for fridge/traffic hiss vs using DaVinci Voice Isolation, Supertone Clear, or RX Dialogue Isolate
- Controlling empty-room reverb tails and cutting muddy 280–450 Hz buildup to bring distant backup mics forward
- Why two gentle 40% passes preserve vocal transients far cleaner than one heavy-handed 95% pass
Topic 03
Wind Rumble, Plosives, Lav Rustle & Mouth De-Click
Cleaning outdoor shoots and close-mic interviews where physical air blasts, collar friction, or dry mouth clicks interrupt spoken phrases.
- Applying steep high-pass slopes and dynamic low-shelf EQ to clear wind rumble while protecting 130–180 Hz vocal body
- Using Spectral Repair Attenuate/Replace to erase shirt scratches, chair squeaks, and phone chimes inside active words
- Taming dry mouth clicks and harsh sibilance on sensitive condenser and lavalier microphones
Topic 04
Parallel Dry/Wet Blending, Mic Matching & Room Tone Beds
Reassembling repaired dialogue so Persian consonants (`ق`, `خ`, `ژ`, `چ`) and natural breath stay authentic, and matching backup camera audio to close mics.
- Parallel track blending: pairing an isolated voice track with a filtered original track to restore natural air and consonant edges
- Laying a continuous -50 dBFS clean room-tone bed under edited dialogue so silence gaps never drop to dead digital zero
- EQ-matching a distant shotgun or camera scratch track when a primary lavalier fails mid-shoot
Course Reference Overview
Location Audio Problem & Repair Strategy Matrix
Core practical benchmarks and standards covered as part of this course's curriculum.
| Acoustic Problem | Over-Processed Mistake | Surgical Repair Method | Recovered Result |
|---|---|---|---|
| Echoey Bare Room | 100% AI speech rebuild turning words metallic and lispy | Moderate De-Reverb + 350 Hz mud cut + parallel dry blend | Closer, clearer voice that still sounds like the real speaker |
| Wind & Plosive Pops | Cutting everything below 250 Hz until voices sound like a phone | Targeted sub-115 Hz slope + dynamic plosive attenuation | Clean low end with natural chest warmth preserved |
| AC Hum & Street Hiss | Heavy gating that chops off breath starts and word tails | Spectral noise print + gentle voice isolation over room tone | Quiet background without pumping silence drops |
| Collar Rustle & Clicks | Leaving distracting scratches or muting whole syllables | Spectral Frequency lasso attenuation + subtle De-Click | Uninterrupted spoken clarity across moving interviews |

Program FAQ
Common Questions
Can I bring a real problem audio recording from a client shoot to diagnose and repair during this course?
Yes, testing real compromised recordings is one of the best ways to learn audio restoration judgment. In your Free Online Intro Session, we listen to a sample of your audio, check whether you edit in Premiere Pro/Audition, DaVinci Fairlight, or standalone RX, and plan your sessions accordingly.
How does the Free Online Intro Session work, and how many sessions will I need?
Every course begins with a Free Online Introductory Session where we review the core syllabus together, evaluate your current background and goals, and map out how many sessions you actually need and whether continuing Online ($69 CAD/hr) or In-Person ($99 CAD/hr) suits you best. Session count is never a rigid one-size-fits-all number; it adapts to your own level and pace.
Do I have to commit to a multi-session package upfront?
Never. There is zero upfront package commitment: once your free online intro session maps out your path, any coaching sessions you choose ($69 CAD/hr online or $99 CAD/hr in-person) are scheduled flexibly session-by-session at your own pace.
Are courses taught in English, Persian (Farsi), or bilingual?
Your choice: every session with Iman Adlkhah can be conducted 100% in English, 100% in Persian (Farsi), or naturally bilingual with industry terminology.
