What if I want to record a call, radio or song on my smartphone? ｜ @DIME At Dime

Have you ever wondered, "It's faster to record than to take notes," such as important meetings and important requirements during a call? In this article, recording is more than a memo! Here are some recommended recording apps for your smartphone. In addition to the app, we also have a smartphone recording how-to, so please refer to it.

How to record on iPhone

The recording application "Voice Memos" is pre-installed on the iPhone. It has no complicated functions and has a simple recording / playback configuration. It is also possible to trim the recorded audio data and re-record it by overwriting. The format is m4a, so if you share it on your PC, you can play it on iTunes.

By the way, voice memos cannot be recorded during a call, so if you want to record during a call, you need to record the call in another way.

Why can't I record a call with Voice Memos?

As mentioned above, the recording app "Voice Memos" pre-installed on the iPhone is an easy-to-use app, but you cannot record during a call. So why can't I record a call with Voice Memos? That's because Apple's products are sold all over the world, and there are recording laws in each country and region.

What is secret recording?

"Recording the contents of a call without the consent of the other party" is called "secret recording", but secret recording does not fall under "criminal activity" in Japan. In countries other than Japan, secret recording does not seem to be considered a criminal act in countries such as Italy.

However, in Germany and the states of Florida and California in the United States, you may be exposed to criminal law without the consent of the two parties or the consent of all the parties involved in the call.

Voice Memos cannot record voice during a call because of the laws of each country.

How to record during a call on iPhone?

There are two main ways to record the voice of a call on your iPhone. One is to record the call voice using the recording app. This will be introduced in the "Smartphone app that can record calls" below. Another way to record a call is to use an external recorder. This will also be introduced in the "IC recorder that can record calls" described later.

Does your Android smartphone have a standard voice recorder?

Although some models of Android OS-equipped smartphones come with the voice recorder app pre-installed, most models do not have the voice recorder app as standard equipment.

Therefore, if you are using an Android smartphone, you need to install the recorder app from the Play Store.

Can Android smartphones record while playing music?

Android smartphones have apps that allow you to record external audio while listening to videos and music. If you want to record while doing other work, you should install "Super Voice Recorder".

Price: Basic free Features: CBR mode and VBR mode can be switched. Since it can run in the background, you can record while using other apps. Also, since the internal audio (audio emitted from the smartphone) is not recorded, you can record only the external audio while enjoying videos and music.

Recommended recording microphone for smartphones

In this item, we will introduce a microphone (recorder) that can be attached to a smartphone for recording as one of the recording methods other than the application.

A collection of convenient smartphone recording apps

This item introduces a recording app, not an external recorder.

A smartphone app that can also record calls

It would be convenient to have an app that can record the voice during a call, such as when you want to deal with troubles or when you want to make a note of important requirements.

If you are concerned about the sound quality during recording, we recommend the "Voice Recorder" distributed by Sony Mobile Communications. You can select the sound quality when recording as shown in the figure below. You can set it to the highest [WAV] to make it easier to hear, but you can also set it to the standard [AAC] to give more storage space.

Radio voice recording app that can record internal voice

Have you ever watched the radio and thought "I want to record it for myself"? In such a case, we recommend the "Recording Radio Server" app, which can record radio sound sources.

How long can you record on your smartphone?

If you are using an app with unlimited recording time, you can record up to the maximum storage capacity. The size of one file depends on the sound quality and recording status, but please see the number for reference.

These two files are files recorded for 20 seconds with the "Super Voice Recorder" introduced in "Can Android smartphones record while playing music?" Above. The recording format is CBR (constant bit rate) and 32 kbit / s. You can see that both files are about 80KB in size.

If you save a 20-second file (80KB) recorded under the above conditions on a smartphone with 64GB of storage, you can save about 838,8861.3 audio files, which is a simple calculation.
