The right voiceover recording format depends on where the audio will be used and what the client or platform accepts. A polished read can still require extra editing if the file has the wrong format, sample rate, bit depth, or channel setup. Before recording, get the delivery specifications in writing and match your session settings to them. Understanding a few common terms makes that conversation straightforward and helps you deliver audio that is ready for its next step.
Choose a File Type
WAV is an uncompressed format commonly used for recording, editing, and professional delivery. It preserves the recorded audio without the data reduction used by compressed formats, making it a dependable choice when a client plans to process or mix the voiceover. WAV files are larger, so confirm how the recipient wants them named, organized, and transferred.
MP3 compresses audio to create smaller files that are convenient for review, web playback, or situations where the recipient specifically requests it. Compression can discard audio detail, and repeated conversions may reduce quality further. Keep an uncompressed master when possible, then export an MP3 copy if the brief calls for one. Do not assume a smaller file is acceptable as the final deliverable.
Match Sample Rate and Bit Depth
Sample rate describes how many times per second the audio is measured during digital recording. Common project settings include 44.1 kHz and 48 kHz. Video and broadcast workflows often specify 48 kHz, while other projects may request 44.1 kHz or a different setting. Follow the project requirements rather than changing the rate based on habit.
Bit depth affects the recording’s available dynamic range and headroom. A 24-bit WAV is a common recording choice because it supports clean editing without requiring the voice to be recorded unusually loud. A client may request a different bit depth for delivery. Confirm both sample rate and bit depth, since a correct file extension alone does not mean the audio meets specifications.
Confirm Delivery Details
Ask for the technical specifications before the session. Confirm the file type, sample rate, bit depth, mono or stereo requirement, and whether the recipient wants raw audio or edited files. Also ask about peak level or loudness targets, head and tail room, file naming, separate takes, and whether breaths or mistakes should be removed. These details can change how you record and export.
Request a sample file, delivery template, or written specification when instructions are unclear. If the recording will be uploaded to a platform, check its current accepted formats and limits rather than relying on assumptions. Clarify who will handle noise cleanup, compression, and other processing. A short confirmation message before recording can prevent avoidable revisions after delivery.
Check the Export Before Sending
After recording, export a short test and inspect its properties in your audio software or file details. Verify the extension, sample rate, bit depth, channel count, and duration. Listen from beginning to end for clipping, unwanted noise, cut-off words, or silence that does not match the delivery brief. Make sure the final file opens and plays correctly.
Keep the original session or an uncompressed master until the recipient confirms the delivery is accepted. If you need to convert the file, use your audio software’s export settings and avoid converting back and forth between compressed formats. Label versions clearly so the client can distinguish a review copy from the approved final.
A reliable voiceover delivery starts with clear specifications, not guesswork. Confirm the file type, sample rate, bit depth, channels, and editing expectations before recording, then verify the export before sending it.
