Song Recorder
You Might Also Need
Song Recorder captures a full performance in stereo at forty four point one kilohertz, with echo cancellation and automatic gain off. It is a take ready for practice review or for later processing.
What is Song Recorder?
Press record and the capture asks for stereo at the CD sample rate, keeping the browser's echo cancellation and automatic gain out of the path. The take stops by itself after thirty minutes, and the panel returns a preview and a download.
The capture settings and the intent behind them:
- A channel count of two where the device allows it, so a line-in or a stereo pair comes back as a stereo file.
- Forty four point one kilohertz requested, matching the rate that music delivery and most consumer hardware use.
- Echo cancellation disabled, because it is a speech tool that leaves artefacts on sustained tones.
- Automatic gain disabled so a performance with a quiet verse and a loud chorus keeps its own dynamics.
- A thirty minute ceiling on the take, with the usual preview and download panel afterwards.
- A note in the panel pointing out that separating instruments is a processing step applied to a finished take rather than something capture can do.
The reason the settings lean on stereo and a fixed rate is that the usual sources here are line level rather than a microphone: a phone playing a backing track while you play along, an interface feed from an instrument, or a single stereo pair in a room. Asking for 44.1 kHz means the recorded file lines up with the way music is normally distributed, and leaving automatic gain off means the performance's own dynamic shape survives. What the tool will not pretend to do is separate anything. The honest scope is capture, and the note in the panel says so: taking the parts of a finished mix apart is a job for the isolation tools applied afterwards, not a property of the recording. As with every other capture in this family, the file is built locally from a decode and a 16-bit WAV write, with nothing uploaded.
What it cannot do:
- It cannot separate instruments, despite how the tool is sometimes described; that is post-processing on the recorded file.
- Stereo and forty four point one kilohertz are requests, so a mono interface records a mono take.
- There is no monitoring path, click track or count in, so timing against the backing comes from your own count.
- Thirty minutes is the maximum per take, which is generous for a song but not for a full set.
- No level metering means an input set too high clips silently.
- It records one input at a time, so a band needs a mixed feed rather than separate channels.
Use it to capture a rehearsal, a practice take against a backing track, or a single stereo feed from an interface. Because the dynamics are preserved, the take responds well to later processing: compressing or levelling it in the dynamics tools keeps more of the original performance than a take recorded with automatic gain riding the level during capture would. If the take is only for review, an honest stereo capture with its dynamics intact is more useful than a polished version produced during recording, because you can still hear what needs work.
How to use Song Recorder
- Press record and allow microphone access; stereo at 44.1 kHz is requested with echo cancellation and auto gain off.
- Perform the take, watching the elapsed timer and remembering the thirty minute ceiling.
- Press stop when the performance ends, or let the automatic stop finish the file.
- Check the summary label for channels and sample rate, then download the WAV.
When to use Song Recorder vs related tools
Song Recorder is for capturing a performance in one pass, whether that is a rehearsal, a practice run or a stereo feed from an interface. Microphone Recorder is the right tool when the concern is choosing the input, and Loop Recorder covers building a performance up layer by layer instead. For keeping time against a backing track, Metronome is the companion, and Audio Trimmer trims the take once it is on disk.
