What file type does voice recorder use?
The MPEG-4 codec used to record and play back audio files in the iPhone’s Voice Memo app is compressed using the Advanced Audio Coding (AAC) codec or the Apple Lossless Audio Codec (ALAC). Because the Voice Memo app only records audio data, the “. M4A” file extension is used, rather than the “. MP4” file extension.
What are the optimal settings for audio recording?
For recording speech, an optimal recording level would have the typical voice at about ‑12 decibels and the peak loudness at about ‑6 decibels or ‑3 decibels. However, good recordings can be made with lower recording levels, as may occur due to variations in the loudness of those speaking.
How big is a voice recording file?
Every minute of audio recorded through the iPhone’s default voice memo app requires roughly half a megabyte of storage space. So a 10 minute recording requires about 5MB of space, an hour takes up 30MB and two hours requires 60MB.

What db level should I record at?
You should record vocals at an average of -18dB for 24-bit resolution. The loudest parts of the recording should peak at -10dB and be lowest at -24dB. This is to keep an even balance on the level of the vocals without distortion. Why is decibel range so important when it comes to recording vocals?

How to choose the Best Sound Recording format?
General recommendations for selecting a recording format Sometimes the recording format is determined based on how the target file will be used. Also, it is not feasible to choose a target sound format with a higher quality than the source sound format. This only leads to an increase in the size of the target file.
Can a WAV file be read by speech to text?
If you use WAV files (which are in uncompressed linear PCM format) with Speech-to-Text, the files must be a maximum of 16-bit depth and encoded in a non–floating-point format. The.wav filename extension doesn’t guarantee that the file can be read by Speech-to-Text.
Which is the best uncompressed audio file format?
AIFF is an uncompressed, PCM based professional audio file format. The AIFF uncompressed file format is the professional file used on Apple’s software. This means its a PCM or a Pulse-Code Modulation format that doesn’t compress or delete the audio in any way. You may notice that when recording in Logic, AIFF is one of your two choices.
How does the MP3 format reduce file size?
The MP3 format is a commonly used lossy compression audio format. It essentially reduces the file size by omitting data in the file. By using perceptive audio coding and psychoacoustic compression, the MP3 format retains the quality as close to the original as possible.
