# Audio Post-production Services > Dialogue editing, audio restoration, multilingual mixing, mastering and audio quality control. Platform-specific loudness and delivery preparation. Source: https://www.globaltranslations.org/linguistic-services/audio-post-production What the service covers ### What Is Audio Post-production? Audio post-production is the editing, cleaning, balancing and final preparation of previously recorded sound. It may include removing unwanted noise, assembling dialogue, blending music and effects, adjusting dynamics, synchronising speech and exporting masters to a delivery specification. Unlike voice-over recording or dubbing itself, audio post-production concentrates on what happens **after the recordings are available**. New recording and translation can be arranged separately. Modular services ### What We Can Do With Your Audio #### Dialogue Editing & Assembly Select and trim takes, correct timing, remove unwanted clicks and gaps, and align dialogue with the script or reference picture. #### Audio Clean-up & Restoration Reduce suitable hiss, hum, room noise and recording artefacts while protecting intelligibility and natural voice quality. #### Voice Processing Apply appropriate EQ, de-essing, compression, tonal matching and level balancing to narration and interviews. #### Mixing & M&E Integration Blend dialogue with supplied music-and-effects (M&E) tracks or stems and finish translated voice recordings for international versions. #### Mastering & Loudness Prepare approved mixes for the intended destination, including agreed loudness, true-peak and dynamic-range requirements. #### Technical & Linguistic QC Check audible defects, sync, clipping, channel mapping, file properties and, when requested, speech accuracy and pronunciation. Choose your scope ### Three Ways to Order Audio Post-production #### Voice & Dialogue Clean-up Audio editing, appropriate noise reduction and tonal and volume consistency for voice recordings. **Deliverable:** Cleaned speech or voice tracks. #### Multilingual Mix & Master Integrate new dubbed dialogue or narration with supplied M&E, balance the mix and prepare a final version. **Deliverable:** Final mix and agreed stems where source tracks allow. #### Audio QC & Delivery Verify an existing master against technical requirements and prepare the approved delivery format. **Deliverable:** Checked files and optional concise QC report. Applications ### Audio Finishing for Different Types of Content #### Film, Documentary & Dubbing Language-version dialogue assembly, M&E integration and sound mixing when the required source elements are available. #### Corporate Video & E-learning Voice-over finishing and clear, consistent audio for presentations, explainers and instructional content. #### Podcasts & Interviews Recording clean-up, edit consolidation, dialogue levelling and platform-appropriate audio mastering. #### Advertising & Social Media Short-form audio editing, narration mixing and technical finishing for distribution across specified channels. Delivery specifications ### Loudness Standards & Audio Quality Requirements We deliver audio post-production to the applicable broadcast, streaming or client delivery standard. We measure programme loudness and true peak using ITU-R BS.1770-5 and follow EBU R 128, ATSC A/85 or other applicable platform specifications as required. Every commissioned master is checked against its agreed loudness target, true-peak ceiling, channel layout, format and metadata requirements before delivery. - [ITU-R BS.1770-5 (2023)](https://www.itu.int/rec/R-REC-BS.1770-5-202311-I) — algorithms for programme loudness and true-peak measurement. - [EBU R 128 (version 5.0, 2023)](https://tech.ebu.ch/publications/r128) — European broadcast loudness, including the −23 LUFS reference for its defined application. - [EBU R 128 s2](https://tech.ebu.ch/publications/r128s2) — additional guidance for streaming loudness. - [EBU Tech 3341](https://tech.ebu.ch/publications/tech3341), [3342](https://tech.ebu.ch/publications/tech3342) and [3343](https://tech.ebu.ch/publications/tech3343) — loudness meters, loudness range and production guidance. - [ATSC A/85:2026-07](https://www.atsc.org/atsc-documents/a85-techniques-for-establishing-and-maintaining-audio-loudness-for-digital-television/) — modern guidance for US television and related streaming workflows. Production process ### From Source Tracks to Finished Audio 1. 01Review the briefConfirm target audience, platform, languages, source tracks, rights, delivery format and deadline. 2. 02Edit & restorePerform editing, cleanup and repair; flag defects that cannot reliably be removed. 3. 03Mix & masterIntegrate voices, music and effects and master to the agreed technical target. 4. 04Check & deliverConduct listening and technical QC, then export and name agreed final files. Deliverables ### What You Receive #### Final Audio Master Agreed mono or stereo format with the specified sample rate, bit depth and delivery naming. #### Dialogue / Music / Effects Stems Separate stems where supported by source recordings or approved project sessions. Flattened audio may not be separable cleanly. #### QC Documentation When requested, a summary of measured loudness, true peaks, channel configuration, file properties and identified issues. **Formats:** WAV/BWF and compressed delivery copies as required. 5.1, ADM, Dolby Atmos and other immersive or multichannel delivery must be separately assessed for technical feasibility and specialist support. Prepare your brief ### What Files and Information Do We Need? Provide your content type, approximate duration, languages, destination platform and available source materials: raw audio, dialogue tracks, music and effects stems or M&E, reference video, approved scripts and the client's technical delivery specification. Restoration and source separation depend on recording quality and rights to the material. We assess feasibility before committing to a particular outcome. Frequently asked questions ### Audio Post-production FAQs Editing arranges and cleans recordings. Mixing balances dialogue, music and effects. Mastering prepares the approved mix to meet delivery requirements. Some noise, hum and clicks can be reduced, but severe clipping, missing speech or heavy background masking cannot always be repaired without audible side effects. Yes, subject to rights and project scope. We can assess timing, audible artefacts, levels and language accuracy with appropriate human review. Yes, where suitable dialogue and licensed music-and-effects elements are available. Additional reconstruction may require a separate technical assessment. We use the target agreed for the broadcaster, streaming platform, podcast distributor or client. There is no single correct LUFS value for every programme. Surround, ADM and immersive masters require separate confirmation of equipment, engineering capability, source assets and format requirements; they are not part of the standard offer. Where source tracks or an editable mix session exist, separate stems can be quoted. A single stereo master does not guarantee clean voice, music and effects separation. The agreed checks may cover listening, sync, clicks, clipping, loudness, true peaks, channel mapping, duration, metadata, file format and, if ordered, linguistic consistency.
