What Is Defined As Complex Sound Removal

The general noise reduction process for dialogue editing typically involves removing background hiss or hum and minor incidental noises. More complex and intrusive noises often require additional time and expertise to remove effectively without damaging the overall audio quality. Here are some examples of complex sounds that require additional time and cost:

1. Construction Noise: Sounds of drilling, hammering, or machinery can be particularly challenging to remove.

2. Lawn Mowers: These outdoor noises can intrude on your recording and require specialized removal techniques.

3. Car Horns: Sudden and loud car horns can disrupt the flow of your podcast and be difficult to eliminate.

4. Phone Ringing: An unexpected ring during recording can prove tricky to remove, especially if it overlaps with speech.

5. Air Conditioning or Fan Noise: The variable frequencies of these background sounds can make them harder to eliminate.

6. Sirens: The changing pitch and volume of emergency vehicle sirens can be difficult to remove effectively.

7. Dog Barks or Birdsong: Animal noises, especially when loud or close to the microphone, can pose a challenge.

8. Door Slams or Footsteps: Sudden, loud noises like these can interfere with speech and prove tough to remove.

9. Planes or Helicopters: The low, rumbling noise of overhead aircraft can be hard to eliminate.

10. Echo or Reverb: Room acoustics causing a voice to echo can be very tricky to remove.

11. Appliances: Sounds from kitchen appliances, like a refrigerator hum or a microwave beep, may require complex sound removal techniques.

12. Music or TV Sounds: Background music or television sounds can be extremely challenging to remove without affecting the voice track.

13. Intrusive Sounds During Speech: If a loud noise occurs at the same time as the speaker is talking, it can be especially difficult to remove without distorting the speech.

Audiobook Dialogue Editing Service FAQs

Hiring a professional audio editing service ensures that your audiobook receives meticulous attention to detail and high-quality post-production. Professionals have the expertise and specialized tools to enhance audio clarity, remove unwanted noise, and create a seamless and engaging listening experience.

The audiobook post-production process typically includes tasks such as editing out mistakes or errors, removing background noise or unwanted sounds, adjusting volume levels, ensuring consistency in tone and pacing, adding or adjusting music and sound effects, and mastering the final audio to achieve optimal sound quality.

We use industry-leading tools and software like iZotope RX to reduce background noise, eliminate unwanted artifacts, and ensure pristine audio recordings. The powerful Waves plugins further enhance your audio by providing precise control over equalization, dynamics, and spatial effects. We strive to deliver a final audio product ensuring crystal-clear sound that captivates listeners.

Yes, our audio editing service can address certain mistakes or errors made during the recording process. We can remove small errors, edit out unwanted noises, and make adjustments to ensure a smooth and cohesive listening experience. However, significant mistakes or issues related to the original recording quality may have limitations in correction during post-production.

When we proof your audiobook, we are diligently listening for a variety of potential issues, such as:

  1. Repeated Phrases: These are sections where the narrator might have repeated the same line or sentence twice.
  2. Consistent Narration: We pay attention to ensure that the tone, volume, pace, and overall delivery of the narration are consistent throughout the audiobook. Any inconsistencies can disrupt the listener’s engagement.
  3. Erroneous Sounds: These can be background noises, clicks, pops, plosives, or any other unwanted sound that may have been picked up during recording.
  4. Missed Pronunciations: We check to ensure that all words, especially those that are complex or uncommon, are pronounced correctly.
  5. Gaps in Sections: We ensure there are no unintended silence periods or overly lengthy pauses between sentences or sections.
  6. Editing Mistakes: We look out for any errors that may have occurred during the editing process, such as abrupt cuts, incorrect cross-fades, or unnatural-sounding edits.
  7. Page-Turn Sounds: These are noises made by turning pages of a script during recording. They can be distracting for listeners and need to be removed.

In essence, our proofing process is designed to ensure that your audiobook sounds professional, clean, and pleasant to listen to from start to finish.

The duration of the audio editing process depends on factors such as the length and complexity of the audiobook, the quality of the initial recordings, and the specific editing requirements. We strive to provide a reasonable turnaround time and can discuss timelines based on the specifics of your project. However, we strive to keep the turnaround time for most of our services 3 days for every 60 minutes of raw audio, excluding weekends and holidays. If you submit multiple media files simultaneously, they will be processed in the order they were submitted.

Our primary aim is to ensure your complete satisfaction with the final product. For basic audio editing services, we offer four complimentary revisions. Each revision can consist of multiple edit lists, not just one.

We understand that a more detailed revision process may be necessary for projects requiring sound design. We offer six complimentary revisions for these projects to ensure the audio aligns perfectly with your vision.

Additional revisions beyond these are available at a fee of $20 each. We also offer an unlimited revisions package for an extra fee, providing the flexibility to make any number of adjustments until you are fully satisfied with the final product.

Remember, our goal is to create a captivating audiobook that meets your exact specifications. We’re committed to working closely with you to bring your vision to life.

Absolutely! We strive to ensure your satisfaction with the final product.

Our goal is to deliver an audiobook that meets your expectations and aligns with ACX’s guidelines.

We believe this payment structure allows for a fair and mutually beneficial arrangement. The upfront deposit ensures a commitment from both parties and enables us to allocate the necessary time and expertise to deliver a high-quality audiobook editing service.

The balance payment, due before accessing the completed audiobook, ensures that we receive fair compensation for our work and ensures a smooth handover of the final product to you. Once the balance payment is received, you can download and distribute your professionally edited audiobook.

We value open communication and transparency throughout the payment process. If you have any questions or concerns regarding the payment terms or need to discuss alternative arrangements, please don’t hesitate to contact us.
