Q & A

  • What is Auphonic and how can it be used for post-production of audio in videos?

    -Auphonic is a service that automates the post-production process of audio for videos. It can be used to balance dialogue and music, reduce noise, and enhance audio quality. It offers a free plan for processing up to two hours of audio per month, with paid plans available for more extensive needs.

  • How much audio can be processed for free with Auphonic per month?

    -Auphonic allows users to process up to two hours of audio for free each month.

  • What is the purpose of the Fairlight tab in DaVinci Resolve?

    -The Fairlight tab in DaVinci Resolve is used for audio editing and mixing. It allows users to work on audio tracks, adjust levels, and apply effects to improve the audio quality of their projects.

  • Why might one encounter plosive issues when using a shotgun microphone?

    -Plosive issues can occur when using a shotgun microphone at close range, such as for podcasting. The proximity to the mouth can cause 'p' or 'b' sounds to create a puff of air that directly hits the microphone, leading to unwanted noise.

  • What is the recommended way to avoid plosive issues when using a shotgun microphone up close?

    -To avoid plosive issues, it is recommended to use a foam cover on the microphone and position it off to the side, still aimed at the corner of the mouth, to prevent direct air impact during speech.

  • How can DaVinci Resolve and Auphonic work together to improve audio in a video project?

    -DaVinci Resolve is used for initial audio editing, while Auphonic is used for advanced audio post-processing. Users can export audio from DaVinci Resolve and import it into Auphonic for further enhancement, such as adaptive leveling, noise reduction, and loudness normalization.

  • What does Auphonic's adaptive leveling do for the audio?

    -Auphonic's adaptive leveling evens out the volume levels between music and dialogue, ensuring a balanced audio mix. It also applies compression to reduce the dynamic range, allowing for an overall louder mix without distortion.

  • What is the recommended loudness level for YouTube videos that are mostly dialogue?

    -For YouTube videos that are mostly dialogue, a loudness level of -16 LUFS is typically recommended.

  • Why is it important to match the length of the processed audio from Auphonic back to the video in DaVinci Resolve?

    -Matching the length of the processed audio to the video is crucial to ensure that the audio remains in sync with the visual content. Any changes in length could cause the audio to be out of sync, which would affect the viewer's experience.

  • How can one ensure that the processed audio from Auphonic is in sync with the video in DaVinci Resolve?

    -After importing the processed audio back into DaVinci Resolve, users should align it with the original audio track, ensuring it starts at the same time and is the same length. This can be visually checked and adjusted as needed.

  • What is the recommended audio file format for exporting processed audio from Auphonic?

    -The recommended audio file format for exporting from Auphonic is WAV, specifically 24-bit PCM WAV, as it provides higher quality audio without the artifacts that can be present in MP3 files.

Keywords

💡Auphonic

Auphonic is an automated audio post-production service that helps to clean and enhance the audio quality of videos. In the video, Auphonic is used to balance the levels of music and dialogue, reduce noise, and improve the overall sound quality. It is mentioned as a service that can be used for free up to two hours of audio processing per month, which is sufficient for a YouTuber publishing a weekly video of around 10 to 15 minutes.

💡DaVinci Resolve

DaVinci Resolve is a professional video editing software that also includes advanced audio editing features. The script refers to it as the starting point for the audio editing process, where initial audio issues are identified and the audio mix is prepared for further processing in Auphonic. DaVinci Resolve is used to export the audio for Auphonic and later to replace the original audio with the processed version.

💡Plosives

Plosives are the sounds produced by sudden bursts of air when pronouncing certain consonants like 'p' and 'b'. In the context of the video, plosives can cause audio issues, especially when using a close-talking microphone for podcasting. The script suggests using a foam cover to mitigate plosive problems, illustrating the practical application of audio recording techniques.

💡Adaptive Leveling

Adaptive leveling is a feature within Auphonic that automatically adjusts the volume levels of audio to achieve a consistent loudness. The video explains that this feature is used to balance the dialogue and music, ensuring that they are at appropriate levels relative to each other without manual intervention.

💡Compression

In audio production, compression is the process of reducing the dynamic range of an audio signal to make it sound louder and more consistent. The script mentions setting the compressor to auto in Auphonic, which helps to achieve the desired loudness without causing distortion.

💡Filtering

Filtering in audio processing refers to the use of equalization to remove or enhance certain frequency ranges. The script mentions using 'voice auto EQ' in Auphonic to clean up the audio, which suggests that filtering is applied to improve the clarity and quality of the sound.

💡Loudness Normalization

Loudness normalization is the process of adjusting the volume of audio to meet specific loudness standards, such as -16 LUFS for YouTube. The video script explains choosing -16 LUFS for dialogue-heavy content and setting the maximum peak level to -1.5 dB true peak to ensure the audio is optimized for online platforms.

💡Noise Reduction

Noise reduction is the process of removing unwanted background noise from an audio recording. The script discusses setting the noise reduction to a dynamic level of 12 dB to subtly reduce noise without making the audio sound robotic or overly processed.

💡Remove Breathings

Remove breathings is a feature in Auphonic that lessens the audible breaths between spoken words, which can be distracting in audio recordings. The video script cautions against setting the reduction amount too high, as it can make the audio sound unnatural by completely eliminating breaths.

💡Bounce Mix to Track

In DaVinci Resolve, 'Bounce Mix to Track' is a function used to export the audio mix from the timeline to a new track. The script describes using this feature to prepare the audio for processing in Auphonic, highlighting a key step in the workflow between video and audio editing software.

💡Export Audio Files

Exporting audio files is the process of saving the audio from a video editing project into a standalone audio format, such as WAV or MP3. The script details the steps to export audio from DaVinci Resolve with specific settings for use in Auphonic, emphasizing the importance of choosing the right format and settings for optimal audio quality.
