## Overview Audio Trim by Wiro cuts a single section out of an existing audio recording. You set a start point, then choose either an end point or a clip length. It returns a new audio file that contains only the selected segment, which helps you ship clean clips without a full editor. ## What you can build - Podcast teasers by clipping a quote from a long episode - Short sound bites for social posts - Ringtones or notification sounds from a longer track - Training datasets by extracting consistent-length segments - QA workflows that standardize “first 15 seconds” samples from user uploads - Trimmed intros and outros for voiceovers and narration ## Inputs - One source audio file to trim. You can upload a file or provide a direct file URL. - A required clip start position. Enter it as seconds (example: 12.5) or as a timecode (example: 00:01:02). The start must fall inside the audio. - An optional clip end position. Enter it as seconds or timecode. The end must be later than the start. - An optional clip length (duration). Enter it as seconds or timecode. It is measured from the start. If you provide both an end time and a length, the length is used. - An optional export format for the trimmed file: MP3, WAV, M4A, AAC, FLAC, OGG, or Opus. If you don’t choose one, the output keeps the input file’s format. - An optional bitrate for lossy exports, in kbps. The valid range is 32 to 320 kbps. This setting is ignored for lossless exports like WAV and FLAC. ## Outputs - A single trimmed audio file in the chosen format. - The result is returned as a downloadable file URL hosted on Wiro’s CDN. - The URL is publicly accessible, so treat it as a public link. ## Limitations - The start time must be inside the source audio. - The end time must be later than the start time. - If you set a clip length that runs past the end of the source audio, the clip is shortened automatically. - Bitrate controls only apply to lossy formats. WAV and FLAC ignore bitrate settings. - Corrupt files, broken URLs, or uncommon audio encodings can cause failures or unexpected cuts. - Output files are stored on Wiro’s CDN for a limited time, so download anything you need to keep. ## Safety & compliance - Only upload audio you have rights to process and share. - Don’t use sensitive audio if a public URL is not acceptable for your workflow. - Download outputs you want to keep, then store them in your own private storage.
