Choosing the Right File Formats for Voiceover Recordings

So you’ve recorded a great voiceover, and now you need to save it as a file. But with so many file formats and compression settings available, how do you know which one to choose? TLDR, MP3 and WAV are the most commonly used formats but there are others, so let’s look at your options…

What are the best file formats for voiceover recordings?

When it comes to voiceover recordings, there are three file formats that are commonly used: WAV, AIFF, and MP3.

WAV and AIFF are both lossless formats, meaning that they retain all of the original audio data from your recording. These formats are ideal for professional use, where high-quality audio is paramount. They are also the preferred format for many digital audio workstations (DAWs).

MP3, on the other hand, is a lossy format. This means that some of the audio data is discarded in order to achieve a smaller file size. MP3s are great for online distribution, as they are easy to upload and download, and take up less storage space.

How do I choose the right compression settings for my voiceover recordings?

If you decide to go with a lossy format like MP3, you’ll need to choose the right compression settings. The most important of these settings is the bitrate.

What is bitrate and how does it affect the quality of my voiceover recordings?

Bitrate is the amount of data that is used to represent one second of audio. The higher the bitrate, the better the quality of the audio. However, higher bitrates also result in larger file sizes.

For voiceover recordings, a bitrate of 128 kbps is usually sufficient for online distribution but if you’re looking for higher quality, you can go up to 192 kbps or even 256 kbps. 

What is a sample rate and how does it affect the quality of my voiceover recordings?

Sample rate is the number of samples of audio that are taken per second. The higher the sample rate, the better the quality of the audio. However, higher sample rates also result in larger file sizes.

For voiceover recordings, a sample rate of 44.1 kHz is standard. This is the same sample rate used for CDs.

What is “hearing the corners”?

“Hearing the corners” is a term used to describe the sound of an audio file that has been compressed poorly. See the article What is “hearing the corners”? for more information.

What is a codec and how does it affect the quality of my voiceover recordings?

A codec is a software program that is used to compress and decompress audio files. Different codecs use different algorithms to achieve different levels of compression and quality.

For voiceover recordings, the most common codec is the MPEG-4 AAC codec. This codec is used by most online platforms, including YouTube and Vimeo.

What are the best settings for voiceover recordings intended for online distribution?

For voiceover recordings intended for online distribution, we recommend using the MP3 format with a bitrate of 128 kbps and a sample rate of 44.1 kHz. This will give you a good balance between file size and audio quality.

If you’re uploading to a specific platform, be sure to check their recommended settings. For example, YouTube recommends using the MPEG-4 AAC codec with a bitrate of 128 kbps and a sample rate of 44.1 kHz.

What are the best settings for voiceover recordings intended for professional use?

For voiceover recordings intended for professional use, we recommend using the WAV or AIFF format with a sample rate of 48 kHz or higher. This will give you the highest possible audio quality.

If you’re working with a client, be sure to ask them what format and settings they prefer. Some clients may have specific requirements or preferences.

How do I optimize my voiceover recordings for playback on mobile devices?

When it comes to mobile devices, smaller file sizes are usually better. We recommend using a lossy format like MP3 with a bitrate of 128 kbps and a sample rate of 44.1 kHz. This will give you a good balance between audio quality and file size.

What are the limitations of different file formats and compression settings?

While different file formats and compression settings have their advantages, they also have their limitations. For example, lossy formats like MP3 sacrifice audio quality for smaller file sizes. On the other hand, lossless formats like WAV and AIFF result in larger file sizes, which may not be practical for online distribution.

It’s important to consider the intended use of your voiceover recording when choosing a file format and compression settings. If you’re unsure, it’s always a good idea to consult with a professional audio engineer or producer.

How can I ensure that my voiceover recordings meet the needs of my clients and are suitable for their intended use?

The best way to ensure that your voiceover recordings meet the needs of your clients is to ask them directly. Find out what their requirements and preferences are and adjust your file format and compression settings accordingly.

It’s also important to keep in mind the intended use of your voiceover recording. If it’s for professional use, high-quality audio is paramount.

Choosing the right file format and compression settings for your voiceover recordings can seem daunting at first, but with a little bit of knowledge and guidance, it can be a breeze. Consult with a professional if you’re not sure. Happy recording!
