A comprehensive guide to podcasting and audio production terms. Whether you're just starting out or looking to deepen your knowledge, this glossary covers the essential vocabulary.
The number of bits processed per second in an audio file. Higher bitrates generally mean better audio quality. Common podcast bitrates are 128 kbps (standard) and 192–320 kbps (high quality). MP3 and AAC are the most common codecs.
Distortion that occurs when an audio signal exceeds the maximum level a system can handle. Clipping sounds like crackling or harshness and cannot be fully fixed in post-production. Proper gain staging prevents clipping.
An audio processing technique that reduces the dynamic range by making loud sounds quieter and quiet sounds louder. Used to create consistent volume levels in podcasts.
A type of microphone that uses a thin diaphragm and requires phantom power (48V). Known for sensitivity and detail, making it popular for studio podcast recordings.
Digital Audio Workstation. Software used to record, edit, mix, and produce audio content. Examples include Audacity, Adobe Audition, and browser-based DAWs like PodManager.AI.
The process of segmenting an audio recording by speaker identity. AI transcription with diarization automatically labels who said what in a conversation, essential for multi-guest podcasts.
A rugged microphone type that does not require phantom power. Less sensitive than condenser mics, making it better for untreated rooms. Popular models include the Shure SM7B and Audio-Technica ATR2100.
The difference between the quietest and loudest parts of an audio recording, measured in decibels (dB). Compression reduces dynamic range for a more consistent listening experience.
The process of adjusting the balance of frequency components in audio. Used in podcasting to enhance voice clarity, reduce muddiness, or remove rumble by boosting or cutting specific frequency ranges.
The amplification level applied to an audio signal. Setting proper gain at the recording stage ensures a clean signal without clipping or excessive noise. Target -12 to -6 dB peak level while recording.
The process of managing audio signal levels at each stage of the recording and production chain to prevent distortion and minimize noise. Proper gain staging is the foundation of professional audio.
Metadata embedded in audio files (MP3, AAC) containing information like title, artist, album, artwork, and episode number. Podcast players use ID3 tags to display episode information.
Loudness Units relative to Full Scale. The industry standard for measuring perceived audio loudness. Podcasts typically target -16 LUFS for stereo or -19 LUFS for mono to match platform requirements.
Mono audio uses a single channel, while stereo uses two (left and right). Most spoken-word podcasts are published in mono to reduce file size. Music-heavy or immersive shows may use stereo.
Recording each participant or audio source on a separate track, allowing independent editing, volume adjustment, and effects processing for each voice. Essential for remote podcast interviews.
The level of background noise in a recording, including electronic hiss, room tone, and ambient sounds. A lower noise floor means cleaner audio. AI noise reduction tools can reduce the noise floor in post-production.
An audio processor that silences audio below a set threshold. Used to cut background noise between words or during pauses. Must be set carefully to avoid cutting off quiet speech.
+48V DC power supplied through an XLR cable to power condenser microphones. Provided by audio interfaces or mixers. Dynamic microphones do not require phantom power.
A service that stores podcast audio files and generates an RSS feed for distribution to directories. PodManager.AI includes hosting, eliminating the need for a separate provider.
A screen placed between the speaker and microphone to reduce plosives — bursts of air from P, B, and T sounds that cause low-frequency thumps in recordings.
Really Simple Syndication. A standardized XML format used to distribute podcast episodes to directories like Spotify, Apple Podcasts, and YouTube. The RSS feed contains episode metadata, audio URLs, and show information.
The number of audio samples captured per second, measured in Hertz (Hz). Standard podcast sample rate is 44,100 Hz (44.1 kHz). Higher sample rates like 48 kHz are used for video production.
Written content published alongside a podcast episode. Includes episode summaries, timestamps, links, guest bios, and resources. Good show notes improve SEO and listener engagement.
AI technology that creates a synthetic replica of a person's voice from audio samples. Used in podcasting for generating intros, corrections, translations, and ad reads. PodManager.AI's Real Voice feature uses ElevenLabs for voice cloning.
Waveform Audio File Format. An uncompressed audio format that preserves full audio quality. WAV files are large but used for recording and editing. Final podcast episodes are typically exported as MP3 or AAC.
Web Real-Time Communication. A browser technology enabling peer-to-peer audio and video communication without plugins. PodManager.AI uses WebRTC for low-latency remote podcast recording.
