Professional Audio Quality Control
(QC) & Technical Auditing

High-Precision Audio Compliance and Technical Validation

Quality Control for Film, Broadcast, Podcasts, Audiobooks, and Streaming Media

Technical accuracy is a requirement for media distribution. Whether you are delivering a feature film to a streaming service, an audiobook to a retail platform, or a broadcast spot to a network, your audio must adhere to precise delivery specifications. To ensure your release timeline stays on track, prioritizing the prevention of technical rejections is critical.

TravSonic utilizes a custom-engineered Technical Audit Engine, a workflow developed over two decades of production. This is not a simple automated scan; it is a specialized technical bridge built for high-volume post-production, identifying artifacts, noise-floor issues, and delivery-standard deviations with frame-accurate precision.

Our Core Methodology: Human-in-the-Loop Intelligence

We do not rely on algorithmic analysis alone. Automated tools often generate false positives or overlook subtle technical errors that can compromise a production.

Our Human-in-the-Loop approach ensures that every project benefits from both high-speed machine processing and experienced engineering oversight:

• Automated Auditing: Our system conducts a preliminary scan, flagging possible technical discrepancies with frame-perfect accuracy.
• Engineering Validation: Following the automated scan, our team conducts a manual review of every flagged instance. We filter out false positives and contextually verify if an artifact requires corrective action.
• Customized Compliance: We refine your final report based on your specific delivery requirements and the unique standards of your target distributor. This ensures your project meets all technical targets while preserving the original intent of your mix.

Editorial Auditing: Raw Track & Manuscript Prep

Beyond technical quality control, we conduct a precision audit for raw, unedited audiobook and podcast captures. This service identifies narrative and structural inconsistencies before you begin the editing process. Learn more about our production and editing services here.

Our engine prepares detailed documentation and transcripts with marked, highlighted sections, all referenced with exact timecodes, providing your team with a clear roadmap for:

• Repetition Detection: Automatically locating repeated words, phrases, and unintentional retakes.
• Pacing & Timing: Identifying excessive gaps, dead air, or inconsistent spacing.
• Non-Lexical Content: Highlighting filler words (um, uh, etc.), heavy mouth noise, and unintentional chatter or off-mic background noise.
• Editorial Roadmap: A report ready for your editing team, allowing them to jump directly into the cleanup process using the provided timestamps without the need for a full front-to-back manual listen.

Profanity Audit and Content Compliance

For projects requiring broadcast-safe, clean, or family-friendly versions, we provide a dedicated profanity auditing service to identify and flag explicit content. Our process ensures you maintain the integrity of your narrative while adhering to strict distribution guidelines.

• Context-Aware Detection: We identify explicit language, offensive terms, or sensitive dialogue that may violate platform-specific content policies.
• Actionable Logs: Receive a comprehensive list of all flagged instances with exact timecodes, enabling rapid replacement, bleeping, or cutting.
• Compliance Standards: Whether you are adhering to FCC broadcast regulations or platform-specific “clean” labeling requirements, we provide the documentation necessary to meet your delivery target.

Comprehensive Delivery Compliance

We provide specialized QC auditing tailored to the unique technical requirements of every major media format:

• Audiobooks (ACX/Audible/Retail): Verification of RMS levels, peak values, noise floor ceilings, and strict chapter formatting.
• Film & Television Streaming (Netflix/Amazon/Disney+): Analysis for loudness targets (LKFS/LUFS), true-peak limiting, channel mapping (5.1/Atmos/Stereo), and dialogue-gated compliance. See our Audio Post-Production page for more details.
• Broadcast Television (ATSC A/85/EBU R128): Ensuring adherence to regional CALM Act standards and broadcast-specific loudness and phase requirements.
• Podcasts & Digital Media: Standardizing gain structures, calibrating sample rates and bit depths, and guaranteeing consistent, high-fidelity playback across any listening device.
• Music Streaming: Auditing for dynamic range integrity and peak prevention across platforms like Spotify, Apple Music, and Tidal.

The Value of a Professional Audio Audit

• Distribution Security: Identify high-priority technical issues, such as clipping, phase anomalies, or loudness standard violations, before the final upload.
• Platform-Ready Compliance: Meet the delivery specifications of major networks and platforms. Our workflow is designed to resolve compliance issues on the first pass.
• Streamlined Editorial Workflow: Detailed reports allow your team to navigate directly to problematic areas via timestamped logs. This eliminates the need for manual troubleshooting, allowing your editors to focus on creative solutions.

The Master QC Package

Upon completion, you receive a dedicated Master QC Folder containing:

1. Proprietary Technical Reports (.CSV and .TXT)

A comprehensive, timestamped log of every flagged instance, providing your editorial team with exact coordinates for technical or editorial fixes.

2. Specialized Audition Clips

To accelerate the review cycle, we include a folder containing concise reference clips for each flagged item. These clips include precise pre-roll and post-roll buffers, allowing you to assess the context of any issue without opening your master session.

3. Technical Delivery Validation

As part of our workflow, we provide:

• End-Check Audio: A reference of the final seconds of every file to ensure no tail or cutoff issues.
• Loudness & Spec Verification: Verification of LUFS, Peak levels, RMS, and DC Offset to ensure your masters are broadcast-ready.

Frequently Asked Questions About Audio Mixing

Question: What technical standards can you verify?
Answer: We check against industry-standard delivery requirements, including EBU R128, ATSC A/85 (CALM Act), ACX technical requirements, and platform-specific guidelines for major streaming and broadcast networks.

Question: How long does a typical Audio QC audit take?
Answer: Turnaround varies by project length, but most standard audiobooks, podcasts, or short-form media are processed and manually reviewed within 24 to 48 hours.

Question: Can you provide the final corrected masters or just the report?
Answer: We offer both. You can use our Master QC Package to perform edits in-house, or our engineering team can provide full remedial editorial services to deliver a broadcast-ready master.

Question: What is the difference between an automated scan and a TravSonic Audit?
Answer: An automated scan is a raw list of hits. A TravSonic Audit is a vetted technical deliverable where our team manually verifies every flag to filter out false positives and provide actionable context.
