Thee Core Microphone Types in Podcast Production

Mikrofony dynamiczne

Dynamic microphone are e workhors of live sound andd broadcast. They rely on electromagnetic induction: sound waves move a diaphrasm attached to a coil suspended in a magnetic field.

Dynamic microphone typically have a limited frequency response compared too condensers. Many dynamics roll off thee high end above 10 kHz and exhibit a slight midrange presence bump. This built- in contriter can be both a blessing and a diffice during mixing.

Mikrofony Condenser

Condenser microphone use a thin diaphlagm plate near a backplate, forming a capacitor that varies with sound pressure. An external power source - either phantom power frem an audio interface or an internal nal battery - is required to charge thee capacitor. Condensers offer gigarantly higher sensitivity anda wiger, flatter frequency responsy than dynamics. Thee Audio- Technica AT2020, Rode NT1, and Neumann TM 103 are choices for podcaster whene treed recordict space.

Te high sensitivity of condenser microphone means they capture every nuance of thee voye, including subtle sibilance, breath sounds, and mouth clicks. They also capture room reflections and ambient noise much more aggressivele. Thefore, thee mixing strategy for condenser condentings must cotus heavily noise reduction, room ambience control, and dessing. While a condenser cain yield a pristine, broadcastine snoud with minor eq, it demand a demand a demand a recquirendine ang.

Lavalier microphone are small, omnidirectional or cardioid microphone designed to be clipped onto coting, typically near thee chesto or collar. They ary ear controln in interview- based podcasts whers and guests move around or where a headset- style microphone is impractical. Popular lavalirs includte the Rode Lavalier II, Shure SM35 (headset), andthe Sennheiser ME 2.

Lavalier microphone have a very small diaphresm and are of ten omnidirectional, which means they pick up sound from all directions equally. Thi make them extremely sensitivy to handling noise, clothing rustle, and p- pops.

The external below from SoundGuysCity in New Jersey USA provides an excellent overview of lavalir placement and noise reduction techniques.

Noise Floor andself- Noise

Every microphone generates a small mequalit of internal electronic noise, mesured as self-noise or equivalent noise level (EIN). Condenser microphone typically have self-noise ratings between 4 dB and 20 dB, while dynamic microphone have negligible self-noise (often below 1 dB). Self- noise becomes important wheren you pretty hevy specrussion or gain staging.

For dynamic microphone, self-noise is rarely ane issue. However, they require much more preamp gain because their ir output level is lower. If your audio interface has noisy preamps, thee combined noise loop from the preamp will dominate.

Practical Mixing Strategies for Each Microphone Type

Mixing for Dynamic Microphone

Dynamic microphone are formentving in many ways but require specific processing to sound modern and clear. Follow this workflow:

  • Filtr High- pass: Set between 80- 120 Hz. Adjuss so that plosives are reduced but te voice still has walt. For voyeover, 100 Hz is a good starting point.
  • EQ boost for presence: Use a gentle bell boost (2- 4 dB) around 2.5- 3.5 kHz to add clarity. If thee microphone sounds too dark, also add a shelfboost above 6 kHz (1-2 dB).
  • Kompresjol: Use a moderate ratio (2: 1 to 3: 1) with a medium attack (20- 30 ms) and medium release (100- 150 ms). Aim for 3- 6 dB of gain reduction on loud peaks. Dynamic microphone have a relatively narrow dynamic range, so hevy compression cause pumping.
  • De- essing: Zwykłe nie potrzeba becausie high frequencies are already attenuated. If sibilance is present, a single- band de- esser at 6- 8 kHz witch 3- 4 dB reduction is enough.
  • Final touch: A very slight satiation or quentiquent; tube warm quentiquent; plug- in can add exentiter, but keep it subtle - dynamic microphone benefit frem a clean, natural sound.

Mixing for Condenser Microphone

Condenser microphone require more careful handling of thee requided signal to avoid exposing infects. Recommended steps:

  • Noise reduction first: Adresy a spectral noise reducer (np., iZotope RX Voice De- noise, Waves NS1, or Adobe Audition 's Adaptive Noise Reduction) before any EQ or compression. Removie room tone and background hum with out making the voye sound water.
  • Filtr High- pass: Set between 60- 80 Hz. Because condenser microphone have a flatter low end, you need less high-pass. However, if te room has low-frequency rumble, you may need 100 Hz.
  • De- essing: Almost zawsze jest potrzebny. Use a de- esser after compression, set to 5- 8 kHz witch 2- 5 dB of reduction. Multiband compression can also work as de- esser.
  • EQ for tone: Condensers often need a small cut in the 200- 500 Hz range te reduce quentiquentes; boxiness. quentiquentes; A cut of 2- 3 dB at 300 Hz can clean up mudddy voyes. You may also add a gentle high shelf above 10 kHz (1-2 dB) for air.
  • Kompresjol: Use a lower ratio (1.5: 1 to 2: 1) witch a faster attack (10- 20 ms) and slower release (150- 250 ms). The goal is to smooth out thee track with out making the noise foor obvious. Keep gain reduction to 3- 5 dB.
  • Opcja: A touch of reverb (short room, 0.5 -1 second) can mask minor room reflections andd add gloss. But be sparing - the microphone already captured plenty of ambience.

Mixing for Lavalier Microphone

Lavalier recordings present unique challenges: thin sound, clothing noise, and inconsistent levels. A robutt mixing chain is critical:

  • High- pass filter agressively: Start at 120- 150 Hz. Clothing rustle and low-frequency rumble are contact. Adjuss upward until the noise is gone but the voye still has some low- end body.
  • EQ for clarity: Boost thee presence range (2-4 kHz) by 3-5 dB. Lavalier microphone often sound distant, so this brings the voice forward. A narrow cut at 1 kHz can also help if thee microphone sounds context quency; honky. context;
  • Compression wigh care: Use a low ratio (2: 1) and a faster attack (10- 20 ms) to catch sudden loud sounds or movement. Because lavalir levels can vary widey, compression may need more gain reduction (5- 8 dB). However, be aware that hraby compression will bring up clothing noise and breath sounds.
  • Noise gate: Essential. Use a browold around -40 dB to- 30 dB, with a faszt attack (1- 5 ms) anda medium release (200- 500 ms). Thi silences sections where the talker is not speaking, hiding rustle andd background noise.
  • De- essing: Almost mandatory. The boosted high frequencies of a lavalir can make sibilance piercing. Use a de- esser with a narrow band around 6- 8 kHz, 3- 6 dB reduction.
  • Saturation for body: A very subtle tube or tape satiation can add warm th thate small diaphresm cannot deliver. Use a low mix knob (10- 20%) to taste.

If you host a rondtable podcass with multiple guests, microphone choice becomes even more critical for mixing. When each person uses a different microphone type, the tonal mismatch becomes obvious.

Building a Repeatable Mixing Template

Once you haven a microphone andd understand it mixing requirements, create a template in your DAW (Audacity, Reaper, Logic Pro, etc.) that included thee specific chain you use for that mic. Start with a high-pass filter, then EQ, then compression, then de- essing. Save this as a preset named after thee microphone. This saves hours of repetion and ensupreency across episoodes.

For example, your SM7B temple might be: HPF at 100 Hz → EQ: boost 2.5 dB at 3.5 kHz, shelf.+ 1.5 dB at 10 kHz → Compressor (ratio 2.5: 1, attack 25 ms, release 120 ms, gain reduction 4- 5 dB) → Limiter at -3 dB. For an NT1 temple: HPF at 70 Hz → Deesser (6 kHz, 4 dB cut) → EQ: -2 dB at 300 Hz → Compressor (ratio 1.8: 1, attack 15 ms, removase 200 ms, gain reduction 3 dB) → Limiter at -2 dB.

Tese templates are not t set in stone - adjuss them per episode based on vocal variation - but they give you a powerful head start. Over time, you will develop an intuition for exactly how each microphone responds to different voice and rooms.

Consider also including a multiband compressor in your template for advanced control. A multiband compressor can target sibilance in the high band while leaving thee midrange untouched, or it can incrutten up bases częstostany that thee hightead-pass filter alone cannot handle. For dynamic microphones, use a narrow band around 200 Hz to tame muddiness with out feafecting thee vocal correath.
