Open Audacity, click on “File” > “Open” and select the file you want to convert. Unfortunately the bit depth may not be perfect for our use. Open Audacity. 16-bit matches audio CDs, and is thus suited where the better dynamic range and S/N ratio of CD quality audio is required. 4. Windows WASAPI: This host is the most recent Windows interface between applications (such as Audacity) and the audio interface driver. The bit depth has no impact on the frequency response, which is constrained by the sample rate. * Audacity 2.3.1 would crash if append-recording to a collapsed track. How to set your bit rate in Audacity. 24-bit recording devices are supported The 44.100Hz sampling rate can accurately represent everything we can hear as human beings and more (22.050Hz, while humans can only hear up to 20.000hz). 3. 4. Audacity provides an effective, minimally destructive way to lower the bit rate of an audio file. Lowering the bit rate lessens the quality of the audio file, but also decreases the file size. The Audacity Preferences dialog box displays. Select 44100 Hz as your default sample rate, and 16-bit as your default sample format (this is a standard sampling frequency and bit depth for CD and broadcast quality audio). All tracks exported from the project will default to 44100 Hz. ... Record at 24-bit depth on Windows (using Windows WASAPI or Windows DirectSound host), Mac OS X or Linux ... Change the tempo without altering the pitch. Audacity is available for Windows®, Mac®, GNU/Linux® and other operating systems. Default Sample Rate: Offers a choice of eight sample rates . For linear effects such as filters, gain control, or even quasi-linear effects suchs as envelopes, in principle it could be done when the 16 bit original bit depth is further quantized to 24 bit or 32 bit float or when getting back to 16 bit. In my case, I record at 44.1kHz (so I don't need to perform any sample-rate conversion) and 16-bit (the limit of my hardware), but I have audacity work in 32-bit floating-point mode. The 32‑bit level provides maximum processing flexibility in Adobe Audition. Converts the Sample Format of the current track state to 16-bit integer PCM, 24-bit integer PCM or 32-bit floating point. In some cases this was a bit too drastic, but since you can preview before applying, it's easy to decide if this will work on a case by case basis. Something very important is that the files are in a format that is supported by Audacity; the most usual ones are WAV and mp3.

Bit depth affects file size. ? Bit rate for WAV and AIFF is calculated thus: (sample rate) * (bit depth) * (number of channels) = kbits per second. In Audacity, the lowest sample rate you can record at is 8000Hz (way too low), and the highest is 384000Hz (way too high). LAME is now bundled in with the latest Audacity version. Audacity’s sample rates go as high as 192kHz, and can support recording at 24-bit depth whether you're capturing audio from mics or another source.

A file with a bit depth of 16 has 65,536 amplitude values available to reproduce sounds contained in the file. Version 5.0 of Song Surgeon is available in both a Standard and a PRO model. 3. 2. 22,050 Hz, 8-bit, mono = 1.25 MB per minute. Do that in the beginnig or in the end of the track, where the song fades to silence. Downsampling occurs when converting a file to a lesser bit depth, or in real-time when Audacity plays audio at a lesser bit depth than the bit depth of the track. Good to know: The audio CD standard is 44.100 samples/sec with 16-bit word length. Change Audacity's default quality settings. Audacity's default sample format during recording can be configured in the Quality Preferences or set individually for each track in the Audio Track Dropdown Menu .
