Product Overview of Auphonic
Auphonic is a comprehensive online audio post-production service designed to enhance, optimize, and streamline the processing of audio files, particularly for applications such as podcasting, radio broadcasts, educational content, video creation, and audiobooks.
What Auphonic Does
Auphonic leverages advanced audio processing algorithms to improve the quality of audio recordings. It addresses common issues like inconsistent loudness, background noise, and unwanted artifacts, ensuring that the final audio product meets high standards of quality and compliance with various broadcast and platform specifications.
Key Features and Functionality
Audio Optimization and Balancing
- Auphonic’s multitrack algorithm processes individual and combined audio tracks, including speech from multiple microphones, music, and remote speakers. It balances levels between speakers, music, and speech using the Adaptive Leveler, which corrects level differences and applies dynamic range compression to achieve consistent loudness.
Noise and Reverb Reduction
- The platform offers robust noise and reverb reduction tools. It classifies regions with different backgrounds and automatically removes noise and hum, ensuring a cleaner audio output. Users can adjust the level of noise reduction according to their needs.
Filtering and AutoEQ
- Auphonic includes advanced filtering capabilities, such as high pass filters, to adaptively remove unnecessary or disturbing low frequencies. The AutoEQ feature provides precise sound control by adjusting equalization settings automatically.
Loudness Normalization
- The service allows users to define target loudness parameters, including integrated loudness, true peak level, dialog normalization, MaxLRA, MaxM, and MaxS. This ensures compliance with standards such as EBU R128, ATSC A/85, and requirements for platforms like Netflix, Spotify, and Audible.
Speech Recognition and Transcription
- Auphonic features multilingual speech-to-text capabilities using the Whisper model by OpenAI. It generates transcripts, shownotes, and chapters, which can be edited in a shareable transcript editor. The service also supports integration with other speech recognition services like Google Speech, Wit.ai, and Amazon Transcribe.
Multitrack Processing
- The multitrack algorithm processes multiple input audio files to produce a balanced, high-quality final mixdown. It includes features like denoising per track, adaptive noise gates, and crossgate to decrease noise, crosstalk, and reverb.
Batch Processing and Automation
- Auphonic allows users to upload and process multiple audio files simultaneously, saving time and effort. The platform automates file transfer, publishing, and integrates seamlessly with various podcast hosting platforms like Libsyn, SoundCloud, and Blubrry.
Metadata and Chapters Management
- The service efficiently manages metadata and chapters for audio files, making it easier to organize and publish content. Users can add and edit chapter markers directly within the platform.
User-Friendly Interface and Integration
- Auphonic boasts a user-friendly interface that is easy to navigate. It offers a recording app for iOS that allows for high-quality recording and direct integration with the Auphonic web service for post-processing and publishing.
In summary, Auphonic is an indispensable tool for audio professionals and hobbyists alike, offering a suite of advanced features to enhance audio quality, ensure compliance with broadcast standards, and streamline the audio production process.
