Lossless vs. Lossy Audio: Can You Hear the Difference?

Every time you press play on Spotify, Apple Music, or YouTube, you're hearing a compressed version of the original recording. The question is: does it matter? Here's what you need to know about audio formats, what lossless actually means, and when it's worth paying for.

The Two Categories

All digital audio files fall into one of two buckets:

• Lossless — Preserves every bit of the original recording. No data is thrown away. (WAV, FLAC, ALAC, AIFF)
• Lossy — Shrinks file size by permanently removing audio data the encoder deems "inaudible." (MP3, AAC, OGG Vorbis)

"Lossy" doesn't mean it sounds bad — modern codecs are remarkably good at hiding what they remove. But something is removed, and at lower bitrates it becomes audible: cymbals turn washy, reverb tails get choppy, and stereo width narrows.

Format Comparison

Format	Type	Typical Bitrate	File Size (5min track)	Used By
WAV	Lossless (uncompressed)	1,411 kbps	~50 MB	NullRecords, studios
FLAC	Lossless (compressed)	~900 kbps	~30 MB	Bandcamp, Tidal, Qobuz
ALAC	Lossless (compressed)	~900 kbps	~30 MB	Apple Music Lossless
AAC	Lossy	256 kbps	~10 MB	Apple Music, YouTube
OGG Vorbis	Lossy	320 kbps (max)	~12 MB	Spotify Premium
MP3	Lossy	128–320 kbps	~5–12 MB	Legacy, podcasts

Can You Actually Hear It?

Honest answer: it depends. On laptop speakers or earbuds in a noisy room, 320kbps lossy and lossless are usually indistinguishable. But the difference becomes real when:

• You're using decent headphones or proper speakers
• You're in a quiet environment
• The music is dynamic and detailed (jazz, classical, acoustic, experimental electronic)
• You're listening critically rather than as background

Nu jazz and experimental electronic music — the kind NullRecords makes — is exactly the category where lossless matters most. Dense layering, wide stereo fields, subtle reverb tails, and dynamic range all benefit from uncompressed audio.

What Streaming Services Actually Deliver

• Spotify Free: 128 kbps OGG
• Spotify Premium: 320 kbps OGG (still lossy)
• Apple Music: 256 kbps AAC default, ALAC lossless available (but locked to Apple ecosystem)
• YouTube: 128 kbps AAC (often even lower)
• Tidal HiFi: FLAC lossless (subscription required)

Even the "lossless" streaming tiers come with caveats — you need a supported device, stable bandwidth, and the tracks must have been uploaded in lossless to begin with. And you still don't own the file.

Why WAV?

NullRecords sells in WAV — raw, uncompressed, studio-quality audio. It's larger than FLAC, but it's the most universally compatible lossless format. Every music player, DAW, DJ software, and operating system on earth reads WAV without any codec or plugin.

FLAC is lossless too, but compressed — think of it as a ZIP file for audio. WAV skips the compression step entirely. What leaves the studio is exactly what lands on your hard drive.
