Imagine complex high-integrity components, without joints or welds, from design to finished product in a matter of weeks. Proxima combines Powder Metallurgy (PM) and Hot Isostatic Pressing (HIP) to realise this possibility, creating near-net-shaped parts without the need for bespoke tooling. The result is a reduction in costs, resources and lead times whilst maximising design flexibility.
Proxima’s technology is trusted by leading businesses in the most highly regulated, quality-demanding industries.
Proxima combines Powder Metallurgy and Hot Isostatic Processing (PM-HIP) to manufacture high-integrity components.
| Parameter | Target | Why | |-----------|--------|-----| | Format | (iOS) or Opus (Android 10+) | Best transparency at low bitrate. MP3 introduces "swirly" artifacts on whisper content. | | Bitrate | 256–320 kbps (AAC) / 160 kbps (Opus) | Preserves breath sounds and sibilance. | | Sample rate | 44.1 kHz or 48 kHz | 22 kHz cuts off whisper air. | | Bit depth | 16-bit (or 24-bit if source is 24-bit) | 8-bit adds noise floor. | | Loudness | -16 LUFS integrated (quiet) | Ringtone should start soft, not blast. | | True peak | -3 dB TP | Prevents clipping on phone speakers. | | Duration | 20–30 seconds | Longer = truncated by OS. Shorter = repetitive. |
