TunesKit Audio Capture — Complete Guide to Recording System Audio

How to Use TunesKit Audio Capture: Step‑by‑Step TutorialTunesKit Audio Capture is a desktop application for Windows and macOS that records system audio from apps, browsers, streaming services, and microphones, then saves recordings in common formats (MP3, AAC, WAV, FLAC, M4A, M4B). This tutorial walks you through installing the software, configuring settings, recording audio from various sources, editing and tagging tracks, exporting files, and best practices to get the highest-quality recordings.

System requirements & preparations

• Supported OS: Windows 7/8/10/11 (64‑bit) and macOS 10.10+ (check the latest compatibility on the official site).
• At least 2 GB RAM and 100 MB free disk space recommended.
• Administrative privileges may be needed for driver installation on Windows.
• Close unnecessary apps to reduce CPU load and avoid audio glitches.

Installation and initial setup

1. Download the installer from the official TunesKit website (choose Windows or macOS).
2. Run the installer and follow on‑screen instructions. On Windows, allow any driver or virtual audio device installations required by the app.
3. Launch TunesKit Audio Capture. On first run it may prompt to add programs to capture — the app automatically lists commonly used browsers and media players; you can also drag any executable or shortcut into the program list.

Step 1 — Choose the source app(s) to capture

• In TunesKit’s main window you’ll see an app list. Click the “+” or drag an app to add it.
• For browser audio, add your browser (Chrome, Edge, Firefox, Safari on macOS). For streaming apps (Spotify, Apple Music, Netflix app) add the respective app.
• To capture system‑wide audio including multiple apps, add each app you plan to record from, or use the built‑in system audio option if available.

Step 2 — Configure audio format & quality

1. Click the Settings (gear) icon.
2. Choose output format: MP3, AAC, WAV, FLAC, M4A, or M4B.
   • Use WAV or FLAC for lossless quality.
   • Use MP3 or AAC for smaller files and wide compatibility.
3. Set sample rate (e.g., 44100 Hz or 48000 Hz) and bit rate (for MP3/AAC) or bit depth (for WAV/FLAC). Higher values increase quality and file size.
4. Choose channel: Stereo for most music, Mono only if necessary.
5. Enable or disable system audio mixing, depending on whether you want to capture only the app or all system sounds.

Step 3 — Start recording

1. Make sure the target app is listed in TunesKit and is added as a capture source.
2. Click the app icon inside TunesKit to launch the app (if not already open).
3. Press the red Record button in TunesKit. The app will start capturing audio from the chosen source.
4. Play the audio in the source app (song, video, stream). TunesKit records in real time — recording length equals playback length.
5. Use Pause and Stop controls to manage recording. If you record multiple tracks in one session, TunesKit usually splits them automatically based on silence detection or list item boundaries.

Step 4 — Edit, split, merge, and tag recordings

• After stopping, recordings appear in TunesKit’s recording list.
• Select a track and click Edit to trim start/end, split long recordings into parts, or merge multiple tracks into one file.
• Use the built‑in ID3 tag editor to add or correct metadata: title, artist, album, genre, year, and cover art. TunesKit may auto‑detect tags for many streaming sources, but verify accuracy.

Step 5 — Exporting and saving files

1. Select one or more tracks from the recording list.
2. Click Convert or Export. TunesKit will process and save files in the chosen output folder.
3. Check the output folder to verify files and play them with your preferred media player.

Recording from special sources

• YouTube and other browser streams: add your browser to TunesKit and record while playing the video. For better control, use the browser’s fullscreen and disable notifications.
• Protected or app‑embedded players (some DRM‑protected streams): TunesKit may still capture the sound output but not decrypt protected video or bypass DRM restrictions. Recording DRM content may violate terms of service in some jurisdictions — ensure you have the right to record.
• Microphone + system audio: enable microphone capture in settings (if available) and choose whether to mix system audio and microphone into a single track or separate tracks (if supported).

Troubleshooting common issues

• No audio captured: confirm the correct app is added, system volume isn’t muted, and output device is active. On Windows, check that the virtual audio driver installed by TunesKit is enabled.
• Low quality or noise: increase sample rate/bit depth, close CPU‑heavy apps, update audio drivers, and ensure direct capture from the target app rather than via speakers+mic loopback.
• Tracks not splitting: adjust silence detection thresholds in settings or manually split files in the editor.
• App crashes on launch: reinstall TunesKit, update OS, or run as Administrator on Windows.

Legal and ethical notes

Recording audio from streaming services, copyrighted material, or paid content may breach terms of service or copyright law in some regions. Use TunesKit for personal, non‑infringing recordings (e.g., capturing personal audio, lectures, interviews) and follow applicable laws and service agreements.

Tips for best results

• Use lossless formats (WAV/FLAC) for archival; convert to MP3/AAC for portable devices.
• Record at 44.1 kHz or 48 kHz and 16–24 bit for music.
• Close anti‑virus or audio apps that might interfere during recording.
• Add meaningful ID3 tags and cover art immediately to keep your library organized.
