Vinyl to Digital Calculator

How Vinyl-to-Digital Conversion Works

Converting vinyl records to digital files involves capturing the analog audio signal as digital samples, then choosing a file format that balances quality and file size. The key technical parameters are sample rate and bit depth.

Core digital audio specifications:

• Sample rate: How many times per second the analog waveform is sampled (Hz)
• Bit depth: How many bits describe each sample’s amplitude (determines dynamic range)

CD quality standard: 44,100 Hz / 16-bit

Dynamic range (dB) = 6.02 × bit depth

• 16-bit: 96 dB dynamic range
• 24-bit: 144 dB dynamic range (exceeds human hearing)

Vinyl’s practical dynamic range: ~60–70 dB once surface noise is counted, which makes 24-bit capture overkill for playback but useful while editing.

File size calculation:

File size (MB) = (Sample rate × Bit depth × Channels × Duration in seconds) ÷ (8 × 1,048,576)

Worked example, one LP side of 22 minutes:

At 44,100 Hz / 24-bit / stereo (2 channels) / 1,320 seconds:

Size = (44,100 × 24 × 2 × 1,320) ÷ 8,388,608 = 333 MB (uncompressed WAV)

At 48,000 Hz / 24-bit: 363 MB. At 96,000 Hz: 726 MB.

Recommended workflow:

1. Capture at 48 kHz / 24-bit (highest common standard)
2. Clean and restore in software (iZotope RX, Audacity)
3. Export masters as FLAC (lossless compression, ~50% smaller than WAV)
4. Create 320 kbps MP3 for portable listening. That is about 76% smaller than a CD-rate WAV and 93% smaller than a 24-bit/96 kHz one, and on a vinyl transfer it is very hard to pick out by ear.

Format comparison, one 22-minute LP side:

Sample rate is doing as much work as bit depth in that table, so a “24-bit” figure quoted without one is not telling you much. The calculator above uses 96 kHz for its hi-res rows and 44.1 kHz for its CD rows, which is why its 24-bit number is roughly double the 333 MB you may see quoted elsewhere.

The one thing you cannot speed up

Recording is real time. A 500-record collection is about 370 hours of playing whatever else you do, and no faster computer changes that. What you can control is everything around it, and that is where projects die: cleaning, setting levels, splitting each side into tracks, and typing in the metadata. Budget it honestly at the start, or the boxes go back in the loft after forty records.
