10 home studio sound cards and audio interfaces for professional voice-over recordings

• RME Babyface PRO: Used by myself and everyone else in the VoiceProductions team, including Jimmy, Bernard and Aurora. A very good card, though on the expensive side. Difficult to install, not great for beginners.
• Scarlet Focusrite: A good card for beginners, plug and play. Not without issues, as there's limited tweakability. There's now software for additional routing options, but it's not all-encompassing. Often used for singing or rap in small studios. Quite affordable, but if you're investing in a new mic, it might be worth upgrading this too.
• Behringer UMC 202HD: An affordable option with many possibilities. Not the warmest sound but good for starters.
• Universal Audio Apollo Solo / Twin: A wonderful card, expensive but not prohibitively so. Beautiful sound and lots of control.
• SSL 2: Not too expensive, very solid for what it does. Comparable to a Ford - well-made but not winning any F1 races.
• Audient ID Series (e.g., ID 4): Very well-made, beautiful sound. Easy to work with.
• Tascam: Has been making recorders for a long time. Generally okay, though models like HN, H2N, H4N, and H6N can introduce noise when plugging in an external mix due to insufficient grounding. Not the best option for VO.
• DBX 286: Known from large studios, it's a strip so it needs to be built into a rack. Works best in combination with other equipment in a strip. Very good, not easy for a beginner.
• M-Audio: Known for affordable cards. Easy to use but doesn’t always offer a deep, warm sound. Suitable if you don't need that, for example, with a high female voice.
• Apogee Duet 3: An expensive card with a very nice sound. Apogee has a range of equipment, of which this might offer the best price-quality ratio.

The sound card is as crucial as the microphone. If either is subpar, you'll inevitably end up with poor results. When it comes to sound cards, bigger often does mean better. While this isn't always the case with microphones, it's almost a certainty with sound cards. A card under 100 euros will never deliver the same quality as one costing several hundred euros. Think of it this way: if the microphone is the ink, then the sound card is the gloss. The card adds warmth, color, and depth to your recordings.

Watch out for USB mics. The sound card is built into the microphone, making it so small that the conversion from analog to digital is rarely satisfactory. Good for personal use, not for professionals.

Newer isn't always better. Sound cards can remain effective for a long time. I know professional recording studios using sound cards from the 70s that still sound amazing. So, a second-hand card could be a viable option if you're on a tight budget.

When looking for a professional sound card to record audio, understanding certain functions and terms can help you make an informed decision. Here’s a rundown of essential features and terminology.

This determines the resolution of your recording, affecting the dynamic range and noise floor. A bit depth of 24 bits is standard for professional recordings.

This is the number of samples of audio carried per second, measured in Hz or kHz. Higher sample rates capture more detail. For voice-overs, 44.1 kHz or 48 kHz are commonly used, but some professionals prefer 96 kHz for its increased clarity.

The delay between input into the microphone and output from the sound card. Low latency is crucial for real-time monitoring without noticeable delay. In voice-over work, where timing and delivery are everything, high latency can disrupt the flow of recording, making it difficult to sync voice-overs with video or other audio elements. Factors affecting latency include the audio interface's drivers, the computer's processing capabilities, and settings within your recording software.

To minimize latency, it's essential to choose an audio interface with robust, low-latency drivers that are compatible with your operating system and recording software. Utilizing drivers like ASIO (for Windows) or Core Audio (for Mac) and adjusting buffer sizes in your recording software can help achieve a balance between low latency and optimal performance.

The number and type of inputs and outputs determine how many devices you can connect. For voice-overs, at least one high-quality microphone preamp input is essential. Look for XLR inputs for professional microphones.

All condenser microphones require an external power supply to operate. Ensure your sound card provides 48V power if you use such a microphone.

The difference in volume between the quietest and the loudest sound the sound card can process without distortion. A higher dynamic range is better, with professional cards typically offering over 100 dB.

This measures the level of the desired signal to the level of background noise. Higher ratios mean less background noise.

A low THD is crucial for clean, uncolored audio. It measures the sound card’s fidelity to the original audio.

Some sound cards include built-in effects or processing, which can be useful for voice-over work. However, a pure, unprocessed signal path is often preferred for maximum flexibility in post-production.

Direct monitoring allows you to hear your voice directly from the audio interface, bypassing the computer's processing. This feature is crucial for voice-over artists, as it enables real-time monitoring of your performance without the distraction of delay. Direct monitoring provides immediate feedback, essential for maintaining the natural flow and ensuring precise timing in voice-over work.

Most contemporary audio interfaces include a direct monitoring feature, accessible via a hardware switch or software control. Engaging direct monitoring eliminates perceptible latency, offering a seamless recording experience that allows you to concentrate on your performance rather than technical issues.

Sound cards, often internal, handle basic audio processing but may not offer the same quality or connectivity as audio interfaces.

Do I really need an audio interface or sound card? For professional voice recording and music production, an audio interface is essential for high-quality results. While standard PC sound cards can handle basic audio tasks, they lack the quality and features needed for professional work.

Do audio interfaces or sound cards improve sound quality? Yes. Audio interfaces significantly enhance recording quality with better preamps and converters. High-quality sound cards can also improve playback quality but may not match the recording capabilities of dedicated audio interfaces.

What do you plug into an audio interface or sound card? Microphones, instruments, and line-level devices can be connected to an audio interface for recording. Sound cards primarily handle playback and basic recording needs.

Which device offers the best audio quality? Audio interfaces generally offer superior audio quality for recording, with brands like Focusrite, Universal Audio, and Apogee being top choices. For playback, high-end sound cards from Creative and ASUS can enhance audio quality.

Do better devices make a difference? Yes. Higher-end audio interfaces provide better preamps, lower noise floors, and higher sample rates, all contributing to superior recording quality. For playback, a high-quality sound card can offer improved audio fidelity.

Are audio interfaces or sound cards worth it? For anyone serious about music production or voice recording, audio interfaces are a worthwhile investment for their superior recording quality. Sound cards can enhance playback quality but may not be necessary for professional recording tasks.

Compatibility and Requirements:

• iOS and Computer Compatibility: Most audio interfaces support macOS, Windows, and often iOS devices for versatile recording setups. Sound cards are typically designed for desktop PCs.
• MIDI Connectivity: Some audio interfaces and sound cards include MIDI connections for older keyboards and electronic instruments.
• Software Compatibility: Ensure your device is compatible with your preferred digital audio workstation (DAW) software and offers the necessary drivers for optimal performance.

Choosing Between an USB Audio Interface and a Sound Card:

• For Voice Recording and Music Production: An external audio interface is recommended for its high-quality preamps, converters, and versatile connectivity options.
• For General Audio Playback and Basic Recording: A sound card may suffice, but for professional-quality recordings, an audio interface is essential.

Investment Consideration: Investing in a high-quality audio interface is crucial for professional voice recording and music production, offering significant improvements in sound quality and recording capabilities over standard sound cards.
