Stereo Tool Settings ((top))

Here’s a concise write-up for Stereo Tool settings—suitable for a blog, user guide, or forum post.

For Online Streaming (MP3 / AAC)

AGC: On, target –12 LUFS, slower release (2–3 sec).
Multiband: Gentle ratios (2:1), only 2–3 dB of reduction per band.
Limiter: Lookahead 5 ms, ceiling –1 dBTP.
Clipper: Very light or off (use true peak limiter instead).
Stereo Enhancer: 50–60% (streams benefit from mild widening).

Recipe C: Clean & Loud (Podcast / Voice-Over)

AGC: Target -8 dB, Medium (500ms), Use "Voice" mode.
Declipper: Bypass (voice shouldn’t clip).
Multiband: 5-band, but set Band 3 (vocal range) to fastest attack (2ms) and slow release (300ms) for smooth leveling.
Noise Gate: Enable at -65 dB threshold, 10ms attack.
Clipper: Hardness 90% (speech tolerates hard clipping), Strength 4%.
Result: Every word is audible without plosives or pumping.

Part 5: Common Mistakes and How to Fix Them

No matter how many tutorials you watch, you will likely make these errors. Here is the troubleshooting section for your Stereo Tool settings.

Mistake 1: The "Flatline" Waveform

Symptom: Your output looks like a perfect rectangle.
Problem: Clipper is set too hard. Distortion is off the charts.
Fix: Reduce "Clipper Drive" by 6 dB. Increase "Final Limiter Release" to 200ms.

Mistake 2: The "Swishy" Highs (Cymbals sound like rain) stereo tool settings

Symptom: High frequencies sound like white noise or running water.
Problem: MP3 encoding artifacts or too much high-band compression.
Fix: Turn down Band 5 gain by 3 dB. Turn on "Spectral Clipper" set to "Smooth."

Mistake 3: The "Wobbly" Bass

Symptom: Bass volume goes up and down like a wave.
Problem: AGC Speed is too slow for the bass attack.
Fix: In the AGC tab, increase the "Bass Speed" to match the "Mid Speed."

Mistake 4: Phase cancellation (Stereo collapses to mono)

Symptom: Sounds wide in headphones, but empty on a phone speaker.
Problem: Stereo Width is set too high (over 200%) or Bass is out of phase.
Fix: Set Stereo Width to 120%. Turn on "Bass Mono" below 100 Hz.

Stereo Image Control

Image Width: Adjusts the stereo image from mono to wider than stereo. Be cautious with extreme settings, as they can lead to an unstable image on mono playback. Here’s a concise write-up for Stereo Tool settings
Image Center: Allows for shifting the center of your stereo image. Useful for making your mix sound more balanced or for creative purposes.

5. The Final Limiter (Safety Net)

Do not confuse this with the clipper. The limiter catches the stray peaks the clipper missed.

Attack: 1ms (instant).
Release: 100ms.
Look-ahead: 5ms. This is a crucial setting. It gives the limiter time to react before the peak hits.

1. Input & Automatic Gain Control (AGC)

The AGC is the gatekeeper. It tames wild volume swings between songs (e.g., a 1960s jazz tune followed by modern EDM). For Online Streaming (MP3 / AAC)

Key Settings:

Target Level: Usually between -12 dBFS and -6 dBFS. This is the level the AGC aims for before other processing.
Speed: "Slow" (1000-3000 ms) for overall program levelling; "Fast" (50-200 ms) for voice or aggressive pop.
Threshold: Set so that only the loudest 10% of your audio triggers gain reduction.
Max Gain / Max Reduction: Limit how far the AGC can push or pull. (Typical: +15 dB / -15 dB)

Pro Tip: For internet streaming, keep the AGC gentle. Over-AGCs cause "breathing" artifacts.
