The feature to capture audio at any time on a smartphone is highly convenient yet often overlooked. iPhones come pre-installed with a voice recording app, and many Android devices also include similar tools. Additionally, there are numerous free recording apps with diverse functionalities. You can use these apps to document your thoughts, lectures, meetings, concerts, and more.
Steps
iPhone

Open the Voice Memos app. This app allows you to record audio on your iPhone. You can find it in the "Extras" or "Utilities" folder.

Press the red Record button to start recording. The iPhone will immediately begin capturing audio through its microphone.

Point the bottom of the iPhone toward the sound source. For the best audio quality, ensure the bottom of the iPhone, where the microphone is located, faces the sound source. Avoid covering the microphone with your hand and maintain a reasonable distance between the phone and the sound source for optimal recording quality.

Tap the Stop button to pause the recording. You can resume recording by pressing the Record button again. Additionally, you can adjust the starting point by dragging the timeline.

Tap "New Recording" to rename the audio file. A text box and keyboard will appear, allowing you to enter a new name for the recording.

Listen to the recording by pressing the "Play" button. This allows you to review the audio before saving it. You can also adjust the playback starting point by moving the timeline.
Tap the "Edit" button to trim the recording.

Press the "Done" button once you're satisfied with the recording. If you haven't named the recording yet, you'll be prompted to do so.

Play the recording. The recording will be listed in the Voice Memos app. Tap once to play it. You can use the Share button to send the recording to friends, the Edit button to trim it, or the Trashcan button to delete it.

Use another app for recording audio. The iPhone App Store offers numerous recording apps with diverse features that may better suit your needs. Open the App Store and search for "voice recorder" to find a list of options. Be sure to read reviews to choose the app that fits your requirements.
- Some recording apps allow you to add effects, save files in different formats, adjust levels, perform advanced edits, and more.
Android

Look for a recording app on your device. Different Android devices come with various pre-installed apps depending on the carrier. Unlike iOS, there's no standard recording app on Android. Your device might already have one, or you may need to download it.
- Search for apps named "Recorder", "Voice Recorder", "Memo", "Notes", etc.

Download a recording app from the Google Play Store. If your device doesn't have a pre-installed recording app, you can quickly install one from the Google Play Store. Many recording apps are completely free.
- Open the Google Play Store and search for "voice recorder."
- Browse the results and find an app that suits your needs. There are numerous free and paid options. Check user ratings to gauge the app's popularity. Tap on the app to view detailed reviews and screenshots.

Launch the recording app. After downloading, locate the app in the App Drawer and open it. Access the App Drawer by tapping the grid icon on the home screen. Since each app's interface varies, the rest of this guide provides general instructions.

Tap the Record button to start a new recording. When you open the newly installed app, you'll likely be directed to a "New Recording" screen or something similar. Some apps may open a list of previous recordings instead.

Point the bottom of your Android phone toward the sound source. Most Android devices have the microphone located at the bottom. Ensure your hand doesn't block the microphone during recording.

Tap the Pause button to temporarily stop recording. You can pause the recording and resume it by pressing the Record button again.

Windows Phone

Open OneNote. You can use the pre-installed OneNote app to quickly record audio. Look for OneNote in your list of apps.

Tap the "+" button. This action creates a new note in OneNote.
