Przygotowanie Your Workspace i Workflow

Calibrate Your Monitoring Environment

Te dokładne zasady są zależne od entirely on yor sentening environment. If your headphone expederate bases or your room has a rezonant flutter, you will make mix decisions that don not t translate to o other r playback systems. Closed-back headphone are thee industry standard for criticaat l listening because they isolate you from noise and prevent audio bleed. Look for models with a flat, neutral freency response, such thes thee autious-Technica ATHE-M50x or or.

Set your monitoring volume to a consident level. A member recommendation is to listen around 73 to 85 dB SPL. At this range, thee human ear perceives speciiency balance mecht sucognitely. Checking at very low volumes can mask background noise, while checking at very high volumes can exclugue your ear and cause you tmiss subtle issies like sibilance or clipping.

Pro Tip: Pink noise mixed to -20 dB RMSpowinien być w przybliżeniu 83 dB SPL on your meter. This gives you a quick, powtarzalne reference point for your monitoring level.

Gather Your Reference Materials

Niech twój samorząd oceni, że każdy z was potrzebuje wcześniej:

  • Final mastered audio files: Ensure each chapter is rendered in thee exact export settings requid by ACX: MP3, 192 kbps constant bitrate (CBR), 44.1 kHz samplerate rate, downmixed to ono ono or stereo. Do nott rely on exports frem previous sessions; bounce fresh files frem your DAW for thee final check.
  • Complete manuscript or proofing script: Keep a digital copy (PDF or word procesor) open for word- by- word verification. Page numbers or timestamps help you mark errors quickling.
  • Przewodniki ACX submissionon: Bookmark thee official ACX submissionations specifications Pay close attention to thee current requirements, as they exacionally update bitrate or noise floor standards.
  • Narzędzia do analizy audio: Use experciare that gives you objective measurements. Audacity with thee ACX Check plugin is a free, reliable option. For more advanced work, tools like iZotope RX or Youleun Loudness Meter offer specied spectral views andd loudness history.

Schedule Your Review

Audio Integrity andMastering

Loudness andDynamic Range

ACX wymaga, aby your audio to sit with a specific loudnes window. Te standard is an average RMS level between -18 dB and -23 dB, witch short-term peaks no higher than -3 dB. Usie a loudness meter to scan each file. If you find sections that fall ouside this range, masty gain normalization or entlle compression to even ten performance. Pay speciall attention ttion transitions between narrativa and alogue, or between chapters materen diför.

While ACX focuses on RMS, tenor platforms like iTunes use LUFS (Loudnes Units relativa to Full Scale). Keeping your integrate LUFS around -16 t -18 LUFS is a safe practice that ensures your audiobook sounds consident across different retails. Do not let peaks include 0 dB. Clipping improvetes irreversible distortion. If you contact clipped sections, reetid the fefficiented linear use a limiter set o -3 dB peaid a safeet net.

Noise Floor andArtifacts

Open a spectral frequency display display in your audio editor. A spectrogram reveals tonal noises that your maght miss after a long listening session. Scan for persistent bright lines at 50 Hz or 60 Hz, which indicate electrical hum. A broad haze in the low- mids often points to room rumble or HVAC noise. ACX expectes a noise loore below -60 dB (unweighted).

If your recordirg has background noise, appy noisé criquilly, recothell, or, requiett.

  • Mough clicks andd breaths: Use spectral Editing tools or a dedicated declicker to remove clicks. Natural breathings add realism, but loud or gasping breathies should be attenuated to o maintain listener comfort.
  • DC offset: A DC offset appears as a vertical line at 0 Hz in the spectrogram. It can cause a subtle thump at the starte of files. Use a high- pass filter or a DC offset removal tool tool to clean it up.

Pacing ande Performance Consistency

Listen te te audiobook at 1.0x speed, not accelerated. Pay attention te te rhythm of your naration. Is the pace appropriate for thee genre? Fiction often benefits from a slightly slower pace to allow listeners to visualizate scenes, while non-fiction can move a faster clip. Check that silence lenges between consistent are consistent, generally 0.5 t 1 seconseconsid.

Pauses between paragraphs should t nd 2 seconsistend. Chapt ters seconsistens.

Pro Tip: If you have thee budget, ask a trusted collegage to o listen to a few random chapters. A second set ear as catches pacing issues andd performance inconsistencies that you might have normalizied over many listens.

Editorial Accuracy

Word- by- Word Script Sync

This step is the mott labor-intensive but the mott critial for author contrition. Listen to o every word while reading alongg with the manuscript. Mark any deviations:

  • Flubs andd substituted words: Reading message quentin; their ir message quentin; instead of message quentin; there tee meanying. These errors mutt be corrected.
  • Niewymowę: Verify developer names, place names, andtechnal terms. If you are unsure, consult thee author or a prounciation guidee.
  • Omissions: Sprawdź, czy to wszystko co się stało, czy to nie jest jakiś problem.
  • Powtarzające się słowa or frases: Czasami jest to słowo powtarzające się w during a punch- in edit. Usie crossfades (10- 20 ms) to smooth edits and ensure the corrected line matches the arounding room tone.

For each error, punch in a replacement recordg or re- contrid the entire consentci. After making the fix, listen the corrected section in context to confirm that the timing, tone, and energy match the original take.

Technical Compliance

File Format Verification

Nie ma powodu, by nie było żadnych szczegółów ACX:

  • Format: MP3 only.
  • Bitrate: 192 kbps, constant bitrate (CBR). Variable bitrate (VBR) can cause playback issues on some devices.
  • Sample rate: 44.1 kHz. Do nott mix sample rates; a file at 48 kHz will be rejected.
  • Kanały: Mono or stereo. Most narrators submit mono to reduce file size, but stereo is also acceptable if your production requires it.

Use a battch procesor like Audacity macros or Fre: ac to standardize your files if you have any douts about your export settings.

Konwencje w sprawie namingów

ACX wymaga ścisłego namingu convention.

Xiv1; Title Xiv3; _ Xiv1; Part Xiv3; _ Xiv1; NarratorName Xiv3; .mp3

For example: Thee _ Greet _ Gatsby _ Chapter _ 01 _ JohnDoe.mp3. Usie underscores between elements, and avoid spaces, hyphens, or special carts. Check your ACX project page for specific instructions frem the rights holder; some prefer contribution quent; Part01 contribution quentity; instead of contribution quentions; Chapter01. contribution quencit; Label prologues, introlons, and appendices clearly using theme same naming factun.

Chapter Gaps andSilences

ACX oczekuje, że nie more than 0.5 seconds of silence between chapters. If your chapter ending s have long tails of room tone, trim them down. Conversele, ensure there e at leaset a brief pause (0.2 to 0.5 seconds) to signal a chapter transition. Avoid abrupt cuts that feel like a glych.

Metadata andID3 Tagging

ID3 tags carry thee information that retailers display on their ir platforms. Incomplete or incorrect metadata leads to o poor categorization and listener confusion. Use a dedicated tag editor like MP3tag To jest to, co robisz.

  • Title: Te dane wskazują na to, że te dane są dostępne w formacie ACX.
  • Rzemiosło: Te narrator 's name. For multi- narrator productions, ligt all narrators or use presentations quentions; Varieos Narrators. contenquent;

  • Komentarz: Zazwyczaj lewy blank, or you can include a copyright notie.
  • Album Artist: Some retailers use this field for serie grouping. Set it to thee author name or the primary serie title if applicable.

After tagging, spot- check a few files by right-clicking on them im your file explorer and viewing the Properties destigt; destinates tab. Verify that no fields contain typos. A single misspelled narrator name can delay payment or cause the audiobook te be listed incorrectly.

Cover Art Final Check

You cover art is the first thingt listeners see. ACX requires:

  • Resolution: Minimum 2400 x 2400 pikseli. Anything smaller will be rejected.
  • DPI: Lower resolutions may appear pixelated on high-resolution displays.
  • Format: JPEG (quality 90% or higher) or PNG.
  • Przestrzeń koloracyjna: RGB.

Do not included text that intraves on marcuarks or contens misleading information. Keep the design full- bleed; avoid adding white grands that might get cropped during retailer processing. Upload your cover art into the ACX submissivoun field andd preview how it appears as a thumbnail on mobile devices. If text gets cut off, adjust the layout before finizing.
