Voxengo Latency Delay Explained: Causes and Simple Remedies

Best Settings to Minimize Voxengo Latency Delay in Your DAWLatency in a digital audio workstation (DAW) interrupts the flow of music production: monitoring becomes awkward, timing is harder to lock in, and real-time tracking loses its natural feel. Voxengo plugins (such as Span, CurveEQ, and several others) are widely used for mixing and analysis, but they can introduce or reveal latency depending on plugin design and DAW settings. This article explains how latency works, how Voxengo plugins factor in, and — most importantly — practical, step-by-step settings and workflows to minimize latency so you can track, monitor, and mix with confidence.

What is latency and why it matters

• Latency is the time delay between an audio input (e.g., your microphone signal) and the output (what you hear).
• In production, latency arises from audio interface buffering, plugin processing (especially lookahead, oversampling, linear-phase processing), and DAW plugin delay compensation.
• Even small delays (10–20 ms) can be perceptible and disruptive when tracking with headphones or in low-latency monitoring situations.

How Voxengo plugins can introduce latency

• Voxengo offers a mix of zero-latency and latency-inducing plugins.
• Plugins that use linear-phase processing, lookahead, convolution, oversampling, or complex analysis (spectral processing, precise phase alignment) typically introduce latency.
• Example features that add latency:
  • Linear-phase EQs and crossovers (they require buffering to achieve linear phase).
  • Lookahead limiters or compressors (they analyze future samples).
  • Convolution reverb (impulse response length).
  • Oversampling modes increase internal buffer size for processing accuracy.

Tip: Check the plugin manual or interface — many Voxengo plugins report their latency in samples or milliseconds.

DAW-side settings to reduce latency

1. Audio buffer size (ASIO buffer / Core Audio I/O buffer)

   • Lowering the buffer size reduces round-trip latency. Typical values:
     • Tracking: 32–128 samples (depending on CPU and interface).
     • Mixing: 256–2048 samples (more stable; allows heavier plugins).
   • Lower buffer = higher CPU load. If you get dropouts, increase slightly.

2. Sample rate

   • Higher sample rates reduce sample-size latency (in samples) when using the same buffer size. For example, 48 kHz vs. 96 kHz halves the time per sample.
   • Consider CPU cost: 96 kHz reduces latency but increases CPU and disk load.

3. Driver choice

   • On Windows use ASIO drivers (manufacturer ASIO or ASIO4ALL as fallback). On macOS use Core Audio.
   • Use the native driver supplied with your audio interface for best performance.

4. Hardware monitoring vs. software monitoring

   • Use direct/hardware monitoring on your interface when tracking to eliminate round-trip latency entirely.
   • If you need plugin processing for monitoring (e.g., vocal chain), use low-latency settings and enable only necessary plugins.

5. Plugin Delay Compensation (PDC)

   • Most DAWs have automatic PDC. For real-time monitoring, some DAWs have an option to disable PDC for monitoring or to use “Ignore Plugins That Delay” modes—use carefully: it may result in misaligned recorded audio but reduces monitoring latency.

Voxengo plugin-side strategies

1. Use zero-latency alternatives when tracking

   • Replace latency-inducing Voxengo plugins with zero-latency options during tracking. For example, use minimum-phase EQs instead of linear-phase when monitoring.

2. Disable oversampling/lookahead

   • If the plugin has oversampling or lookahead settings, turn them off while tracking. Re-enable them during mixing/rendering as needed.

3. Reduce internal FFT/block sizes (when available)

   • Some analysis or spectral plugins let you choose FFT/window sizes. Smaller sizes reduce processing latency but may affect resolution.

4. Use “preview” or low-latency monitoring modes

   • Some Voxengo plugins include lower-latency modes or options intended for live monitoring — enable these when available.

5. Check and report plugin latency

   • Many Voxengo plugins report latency in samples. Record that number and, if needed, manually delay or adjust tracks so the output is aligned during mixdown if automatic compensation is bypassed.

Practical workflows: tracking vs mixing

• Tracking session (low-latency priority)

  1. Set buffer size to 32–128 samples.
  2. Use interface direct monitoring if possible.
  3. Disable or bypass latency-inducing plugins (linear-phase EQs, convolution reverbs, oversampled processors).
  4. Use lightweight Voxengo plugins with zero-latency modes or replace them with low-latency substitutes.
  5. Record dry if you plan to apply heavy processing later.

• Mixing/mastering session (quality priority)

  1. Increase buffer to 512–2048 samples for stability and plugin headroom.
  2. Re-enable oversampling, linear-phase settings, lookahead, and convolution processing for best quality.
  3. Allow your DAW to perform full plugin delay compensation for perfect phase and timing alignment.
  4. Render stems or final mix with full-quality settings.

Specific DAW tips (common DAWs)

• Ableton Live
  • Preferences > Audio: lower Buffer Size, enable “Reduced Latency When Monitoring” to minimize delay but be aware this temporarily disables PDC for monitored tracks.
• Pro Tools
  • Use Low Latency Monitoring (LLM) for recording. Avoid plugins that are not LLM-compatible on monitored tracks.
• Logic Pro
  • Audio preferences set I/O Buffer Size low for recording; Logic’s Low Latency Mode bypasses plugins that introduce latency.
• Cubase
  • ASIO Guard and Constrain Delay Compensation options help manage latency — use Constrain on while tracking.

Measuring and compensating latency

• Measure plugin latency in samples (many plugins show this in their interface). Convert to ms:
  • ms = samples / sample_rate * 1000
  • Example: 256 samples at 48 kHz → 256 / 48000 * 1000 ≈ 5.33 ms
• If your DAW doesn’t auto-compensate during recording/monitoring, you can manually shift audio or add delay plugins to align tracks during mixing.

Troubleshooting common latency problems

• Crackles/pops when lowering buffer: raise buffer slightly until stable.
• Vocals sounding delayed while monitoring with plugin chain: bypass high-latency plugins or use hardware monitoring.
• Misaligned tracks after disabling PDC: enable compensation for mixdown or manually nudge regions by the known latency amount.
• CPU overload at low buffer: freeze or commit tracks, or increase buffer for tracking moderate-sized sessions.

Quick checklist (tracking)

• Buffer: 32–128 samples
• Use interface direct monitoring: Yes, if possible
• Disable: linear-phase, lookahead, convolution, oversampling
• Replace heavy Voxengo plugins with zero-latency alternatives or bypass
• Sample rate: consider 48 kHz (or higher if CPU allows)

Quick checklist (mixing)

• Buffer: 512–2048 samples
• Enable oversampling, linear-phase, lookahead, convolution as needed
• Allow full plugin delay compensation
• Render with highest quality settings

Final notes

Minimizing latency is usually a trade-off between immediacy and processing quality. For tracking, prioritize low buffer sizes and zero-latency monitoring; for mixing, prioritize quality and allow latency-inducing processes. Keep a flexible workflow: monitor clean and record dry if necessary, then reintroduce Voxengo’s higher-quality modes for final mixing and mastering.
