LoopRec: Record Mac System Audio and Microphone During Headphone Interviews
Online interviews are easy to remember in broad strokes and surprisingly hard to recall in detail. A few hours later, the exact questions, follow-ups, and wording may already be unclear. That makes it difficult to write an accurate interview recap or identify what to improve before the next round.
LoopRec is a lightweight native macOS app that records Mac system audio and microphone input at the same time. It is designed for interviews, meetings, research calls, and other conversations you are allowed to record.
If you join an interview from a shared office, bedroom, coworking space, or any location where speakers are impractical, you can keep wearing headphones. LoopRec captures the audio played by your Mac together with your own microphone, then saves the conversation locally as an M4A file for review or transcription.

Important: Always follow applicable recording laws, company policies, and platform rules. Inform other participants and obtain consent whenever required before recording an interview, meeting, or call.
Why Interview Review Needs Both System Audio and Microphone Input
Recording only your microphone preserves your answers but loses the interviewer's questions. Recording only system audio captures the other side but leaves out your responses.
A useful interview recording needs the full context:
- the interviewer's questions and follow-ups;
- your answers, pauses, and explanations;
- the timing between each question and response;
- enough audio context to create an accurate transcript;
- a reliable record for identifying gaps before the next interview.
LoopRec can record system audio, microphone input, or both sources together. Unlike a screen recorder, it focuses on audio rather than video. You do not need to capture your screen, store a large video file, or extract an audio track afterward.
Can You Record an Online Interview While Wearing Headphones?
Yes. The key is to capture the Mac's system audio directly instead of relying on an external phone or room microphone.
A phone placed beside a laptop may pick up keyboard noise, room echo, and other people nearby. It also works poorly when the interview audio is playing through headphones. A full screen recorder can capture audio, but it may create a much larger file and include visual information you do not need.
LoopRec provides a more direct workflow:
- Open LoopRec on your Mac.
- Select system audio and microphone as the recording sources.
- Connect your headphones and join the interview normally.
- Check both audio-level indicators before the conversation begins.
- Start recording after informing participants and obtaining any required consent.
- Stop when the interview ends and save the local M4A file.
Because LoopRec captures the system audio generated by your Mac, the interviewer's voice can still be recorded while you listen through headphones.
Key Features of LoopRec for macOS
Record Mac System Audio and Microphone Together
LoopRec can capture the sound played by macOS and your microphone input in the same recording session. Separate volume controls and live level indicators help you detect a muted microphone, an incorrect input device, or an unbalanced audio source before the interview starts.
Native Swift App, About 1.2 MB
LoopRec is built natively with Swift for macOS 15 and later. The app is approximately 1.2 MB and stays focused on audio recording. It does not add video editing, camera capture, streaming layouts, or other features that are unnecessary for interview review.
Local M4A Recording
When a recording ends, LoopRec mixes the selected audio sources and saves the result as an M4A file in a local folder chosen by the user.
According to the official product information:
- recordings stay in the folder you select;
- recordings are not uploaded to a LoopRec server;
- no LoopRec account is required;
- the app does not include advertising or analytics SDKs.
Review the current privacy policy and App Store disclosures before using the app with sensitive conversations.
Smaller Files Than Screen Recordings
If you only need the conversation, recording video is unnecessary. An audio-only M4A file is generally easier to store, transfer, replay, and import into transcription software than a full screen recording.
This is especially useful for candidates who conduct several interviews and want to maintain a structured archive without keeping large video files.
Ready for Transcription and Interview Notes
The recorded M4A file can be imported into Feishu Minutes or another transcription service that supports the format. You can also use a local transcription workflow if you prefer to keep processing on your own device.
Transcription accuracy depends on audio quality, language, speaker overlap, accents, and the service you choose. Checking both recording levels before the interview can improve the result.
Free Sessions Up to 40 Minutes
LoopRec is free to try. The free version supports recording sessions of up to 40 minutes. Users who need longer individual sessions can choose the optional one-time LoopRec Pro upgrade. Current pricing and regional availability are shown in the Mac App Store.

A Practical Interview Review Workflow
A recording is most valuable when it becomes part of a repeatable review process. After an interview, use this simple four-step workflow.
1. Listen Once Without Pausing
Replay the conversation from beginning to end. Focus on its overall structure: what the interviewer cared about, where the discussion changed direction, and which topics received the most follow-up questions.
2. Write Down the Exact Questions
Separate the initial question from later follow-ups. What first sounded like one broad topic may actually contain several evaluation points.
For example, a system-design question may include separate concerns about scale, failure handling, data consistency, observability, and cost.
3. Compare Each Question With Your Answer
Review whether your answer addressed the actual question. Mark places where you:
- answered too broadly;
- missed a technical constraint;
- gave an opinion without evidence;
- failed to explain your personal contribution;
- had a strong example but presented it too late;
- needed a diagram, metric, or clearer structure.
4. Create a Short Improvement List
Do not turn every recording into a long report. Extract a small set of actions for the next round, such as reviewing one technical topic, improving one project story, or preparing a clearer answer to a recurring question.
The goal is not to record everything indefinitely. It is to replace unreliable memory with a reviewable record, then convert that record into better preparation.
More Than an Interview Recording App
Although LoopRec works well as a Mac interview recording app, the same dual-source audio workflow can help with other permitted recording scenarios:
- remote meetings;
- research interviews;
- user interviews and product discovery calls;
- online lessons;
- language-practice sessions;
- personal presentation review;
- technical discussions that need accurate notes.
LoopRec is not intended to replace professional screen-recording software. If you need video, camera footage, screen annotations, editing, or livestream layouts, a dedicated screen recorder is a better choice. LoopRec is for situations where the conversation itself is what matters.
Privacy, Consent, and Recording Laws
Local storage does not automatically make every recording lawful or appropriate.
Recording rules vary between US states, European countries, employers, interview platforms, and meeting participants. Depending on your location and circumstances, one-party or all-party consent rules may apply. Workplace policies may also prohibit recording even when local law would otherwise allow it.
Before recording, confirm:
- whether the interviewer, recruiter, or meeting organizer allows recording;
- whether all participants must be informed;
- whether explicit consent is required;
- how long the file should be retained;
- who is allowed to access the recording;
- whether the conversation contains personal data, confidential information, or trade secrets;
- whether an external transcription service is permitted to process the file.
When in doubt, ask before recording. Do not use LoopRec for covert recording.
Frequently Asked Questions
How do I record system audio and microphone on a Mac?
Use a Mac audio recorder that supports both system audio and microphone input. LoopRec is built for this workflow on macOS 15 or later. It captures the selected sources and saves the mixed result as a local M4A file.
Can I record an interview while wearing headphones?
Yes, if the recording app captures the Mac's system audio directly. LoopRec can record the audio played by your Mac together with your microphone while you listen through headphones. Always obtain any required permission before recording.
What is the best way to record an online interview on a Mac?
If recording is permitted and you only need the conversation, a dedicated audio recorder is usually simpler than recording the entire screen. Test the system-audio and microphone levels before the call, use headphones normally, and save the output in a controlled local folder.
Can LoopRec record Google Meet, Zoom, Microsoft Teams, or browser audio?
LoopRec records system audio produced by the Mac rather than depending on a specific meeting platform. Compatibility can still depend on macOS permissions and the audio configuration in use. Test the setup before an important interview and consult the official system-audio guide if needed.
Does LoopRec upload my recordings?
The official LoopRec website states that recordings remain in the local folder selected by the user and are not uploaded to LoopRec's server. If you later import a file into a third-party transcription service, that service has its own privacy terms and data-handling policy.
Can LoopRec create an interview transcript?
LoopRec creates the audio file; it does not need to be a transcription platform. You can import the resulting M4A file into Feishu Minutes or another compatible transcription tool. Accuracy varies with audio quality and the selected service.
What version of macOS does LoopRec require?
LoopRec requires macOS 15 or later. Check the current Mac App Store listing for the latest compatibility information.
Is LoopRec free?
The free version supports individual recording sessions of up to 40 minutes. An optional one-time Pro upgrade is available for longer sessions. Refer to the Mac App Store for current prices and availability in your region.
