The best USB audio interface for a PC depends on what you need to connect. The Focusrite Scarlett Solo is best for recording a microphone and guitar with high-resolution audio, while the M-Audio M-Track Duo is better for two-input recording on a straightforward setup. The MAONO P1 suits creators who want PC and mobile connections, and the M-Track Solo covers a single-mic setup. For basic headphone and microphone connections rather than studio recording, the Sabrent adapter is a compact alternative.
| Product | Best for | Key distinction |
|---|---|---|
| Focusrite Scarlett Solo 3rd Gen | Vocal and instrument recording | 24-bit/192kHz recording and switchable Air mode |
| M-Audio M-Track Duo | Two-input recording | Two combo inputs and zero-latency direct monitoring |
| M-Audio M-Track Solo | One mic plus an instrument | Separate mic/line and line/instrument inputs |
| MAONO P1 | Streaming and mobile workflows | Dual USB ports and auto-gain features |
| Sabrent USB Sound Card Adapter | Basic PC audio connections | Simple headphone output and microphone input |
Focusrite Scarlett Solo 3rd Gen
The Focusrite Scarlett Solo is best for a PC user recording vocals alongside guitar or bass. Its two high-headroom instrument inputs accommodate guitar or bass, and its mic preamp is designed for microphone recording. Switchable Air mode adds clarity to acoustic instruments, while Gain Halos help identify levels that could cause clipping.
The listed recording specification is up to 24-bit/192kHz, making it a stronger fit for users prioritizing detailed recording and mixing than a basic USB sound adapter. Choose this model if you want a focused recording interface with higher stated resolution. Its Solo name and listed features indicate a compact setup; choose a model with more inputs if you need to record several sources at once.
M-Audio M-Track Duo
The M-Track Duo is best for PC users who need two inputs for podcasts, vocals, guitar, or line-level sources. It has two combo XLR/line/instrument inputs with phantom power, so it supports different source types without relying on a single input format. Its listed audio resolution is 48kHz.
A 1/4-inch headphone output and stereo 1/4-inch outputs provide monitoring options. The USB/Direct switch supports zero-latency monitoring, which is useful when listening to a live input while recording. Choose the Duo over the M-Track Solo if two inputs matter. Its stated 48kHz resolution is lower than the 24-bit/192kHz specification listed for the Scarlett Solo and MAONO P1.
M-Audio M-Track Solo
The M-Track Solo is best for a PC recording setup that needs one microphone input plus a separate instrument or line input. Its combo XLR/line input includes phantom power, and its second input accepts line or instrument signals. Like the M-Track Duo, it is specified for 48kHz audio.
The interface provides a 1/8-inch headphone output and stereo RCA outputs. Its USB/Direct switch enables zero-latency monitoring. Choose this model if its input arrangement matches your sources and you do not need two combo inputs. It is less suitable than the Duo for recording two microphone or combo-input sources at the same time.
MAONO P1 USB Audio Interface
The MAONO P1 is best for creators who want to record on a PC and connect a phone or iPad in the same workflow. Its dual USB ports are described for simultaneous computer and mobile connections, and its listed device support also includes Mac, iPhone, Android, and cameras. It offers up to 70dB of gain and recording up to 24-bit/192kHz.
Creator-focused features include auto-gain, independent mute controls, and a Stream Mode that sends the voice equally to both channels. ASIO support is listed for lower-latency monitoring. Choose this interface if those streaming controls and connection options suit your workflow. Its multiple modes and controls may be unnecessary for someone seeking only a simple PC recording connection.
Sabrent USB Sound Card Adapter
The Sabrent adapter is best for someone who needs a basic USB audio input and output for a PC, not a full recording interface. It connects through USB Type-A and provides a 3.5mm stereo headphone output and a separate 3.5mm mono microphone input. It is bus-powered and described as plug-and-play, with no separate software or external power required.
Choose it for simple headphone and microphone connections, including systems that support class-compliant USB audio. It does not support a single-plug four-pole headset, power passive speakers, or add surround sound. Its basic stereo connections also make it a poor substitute for an interface with instrument inputs, mic preamps, or recording-focused controls.
Buying Guide: Choosing a USB Audio Interface for PC
How many inputs do you need?
Count the sources you expect to record at the same time. A one-mic setup may suit the M-Track Solo, while the M-Track Duo provides two combo inputs. The Scarlett Solo and MAONO P1 offer different feature sets, so compare their listed input and workflow details against your recording needs before choosing.
Do you need an interface or a sound adapter?
A recording interface is the better fit for microphones, guitars, and recording controls such as gain or direct monitoring. A USB sound adapter such as the Sabrent is for basic headphone and microphone connections. Check the connector type on your headset: the Sabrent has separate headphone and mic jacks and does not support a single four-pole plug.
Which audio and monitoring features matter?
Compare the stated recording resolution if sound capture is a priority: the Scarlett Solo and MAONO P1 list up to 24-bit/192kHz, while both M-Track models list 48kHz. For monitoring, the M-Track models include a USB/Direct switch. The MAONO P1 lists ASIO support and creator-oriented mute and gain controls.
Will it fit your recording workflow?
Consider whether you record only on a PC or also use a phone or tablet. The MAONO P1 is described with dual USB connectivity for a computer and mobile device. For a PC-only setup, input count, connector types, headphone output, and direct monitoring may be more important than mobile connections.
