Should I record voice in mono or stereo for a narration project?

For a typical one-microphone narration, start with mono. Mono holds one channel; stereo holds two. Audacity’s manual recommends mono for a single-microphone voice recording. It notes that choosing stereo for one microphone can create two identical copies and a larger file. [S1][S2]

That does not mean stereo is automatically wrong or that mono guarantees a particular sound quality. The useful question is what your microphone is capturing and what your editing project requires.

Before you record a full take, make a short test in the format you intend to use. Listen back, confirm that the expected channel or channels contain the voice, and check that the project accepts the recording. If you are following a client, studio, or editor’s delivery specification, use that specification rather than guessing.

Stereo makes sense when the recorded source is genuinely two-channel, or when your project specifically calls for stereo capture. The Audacity manual recommends stereo for music and other sources that are already stereo; its guidance is about Audacity’s recording setup, not a universal delivery rule for every project. [S1][S2]

With two microphones connected to an interface, do not assume that you must combine them into one stereo track. Audacity’s manual recommends recording each microphone to its own mono track. [S1] This keeps the microphone recordings separate in that setup, so they can be handled individually during editing.

For example, if you are recording one narrator with one microphone, mono is a sensible starting choice. If you are recording two people with two microphones in Audacity, separate mono tracks follow the manual’s recommendation. If you are recording a stereo source, stereo may be suitable. Confirm that the software and delivery instructions support your plan.

Ask for the project requirements before recording a long session. In particular, clarify whether the editor wants mono or stereo files, whether separate microphone tracks are needed, and whether you should provide an unedited recording or a finished mix. These questions help you choose a capture setup that suits the intended edit.

If you cannot get an answer in time, choose based on the actual source and equipment, then label your test clearly and check that it opens correctly in the project you will use. For a single-microphone voice recording in Audacity, mono is the manual’s recommended starting point. For a stereo source, the manual recommends stereo. [S1][S2] The guidance does not establish what every editor, platform, or other recording application requires, so it cannot replace a project-specific delivery specification.

Copy and fill in this short request:

“Source: [one microphone / two microphones / stereo source]. Please confirm: [mono or stereo capture], [separate tracks needed?], and [required delivery format]. I plan to record a short test before the full narration.”

Record a few seconds using the actual narration setup, then check three things: the file or track has the channel format you intended; the voice is present where expected when played back; and the recording can be brought into the intended editing project. If you are using multiple microphones, check that their tracks are organized as requested. In Audacity, the manual recommends individual mono tracks for microphones connected through a two-input interface. [S1]

A test can confirm that your setup behaves as expected, but it cannot tell you what an unspecified client or platform requires. Get those requirements from the person or project documentation responsible for delivery. If none are available, record in a format appropriate to your source, keep the test, and note the choices you made so you can repeat them.
